Not if it is doing it at idle as well. Most like be the tappets. Check your oil level and make sure the engine is topped up. Maybe use a thicker oil and this will keep the tappets quite, although this is only a temporary fix.

rebuild

lol

anyway

i doubt it would be the lifters, as they are usually noisy when the motor is cold, and the noise would happen all the time and especially if you leave it without driving for a few days, and the noise would increase in frequency with revs.

what u have explained does not sound like lifters..

try and different oil, i cant think of what it would be...

btw. i wouldnt use those oil additives/flushes if i were you, they might cause more problems than they solve, ie. they gunk can get cleaned of then all get stuck in chunks somewhere else in the engine.

best to just change the oil a few times with cheap oil.

Sorry to hijack, but do u get rid of this? Currently using Castrol Magnatec, after changing from a 15W/40 rating, noise goes away after the oil change but comes back again after a couple of days.

Hey, 15/40 sounds normal, and you should use an oil of similar rating 10/40 or whatever,

i have found that if it is bad, use cheap oil(magnatec or whatever) for about 500-100kms and then change it for oil you would normally use(synthetic of similar weight) which sort of flushes the system.

so i dont think it is the brand of oil, its just that u have one or more sticky lifters. open the bonnet and you can probably hear which ones are bad..

yeah i have seen the guide ur talking about..too bad its not that easy..

cams would have to come out, but i dont think it would be a bad job. i have replaced the cams in rb25.. not really a difficult job i guess just fidly. u just have to have a torque wrench to make sure u attach them back properly and evenly (the cams can crack in half, my exhaust one did!)

when i started the car afterwars one lifter was SO NOISY like crazy!!! i was scared it would be like that forever!!! it was bloody loud. after a good run it quietened down :D

but then again when we put them back in the head was sitting on the ground, not on the bottom end so it made things easy.

:mad:I've got a lifter problem as well... I think? It started about 6 months ago after a major service! But it is weird, because lifters usually tap when the engine is cold. When I first start my car in the morning (cold) it starts and runs at the high rev warm up mode, while it is warming up I have a smoke and coffee, usually about 10-15mins... no tapping. Then all of a sudden the engine slows down once it is warm and the temperature guage says so.... then tap, tap, tap, tap!!! WTF this goes away after a short drive... whats going on?

Just to clear something up. Lifters don't tap. The rockers do. And as for not doing it unless cold. That is incorrect, if you have a sticky lifter it will cause a tapping noise all the time. Sometimes they unstick once the oil has warmed up.

Thicker oil is not really the best option either. A thinner oil will get rid of a noisy lifter more often than not. It is the gunk built up in the lifter that prevents it from filling with oil properly. The thinner oil allows better flow through the smaller spaces thus allowing the lifter to 'pump' up.

As for products. This is your best option to free up a sticky lifter as it doesn't just brake off chunks of gunk and leave it floating around the engine in it's full size (speaking of which, lifter veins are virtually smaller than any other oil passage in the whole engine to to get stuck in anything other than another lifter would be highly unlikely) The product will break down the sludge or gunk into much smaller pieces and then they travel to the sump and eventually go through the oil filter which picks them up.

My Suggestion:

Run Wynns engine flush for 10 km

Drain ALL old oil. Try to use a clear container so you can examine the old oil. You could even go so far as to strain it through paper towel to locate any impurities so that you can identify them.

Change Oil filter

Refill oil with Synthetic grade oil. Somthing like a 10 or a 15 weight.

If the noise is still there, you may have to try manually cleaning them.

If that doesn't fix it then you'll have to buy new lifters. Assuming that is the problem in the first place. I always recommend getting a professional opinion before replacing anything. Especially when those lifter cost $700-$800 for a set.

Lifters

Shims are only spacers which space the buckets to the followers. They come in all different thicknesses for setting valve clearance instead of hydraulic or adjustable.

They can be found on GTR's.

The GTST's don't have shimable buckets, they have hydraulic lifters.

      The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
