Hey guys my sr is making a tapping noise around 2-3k it started last night when I was like 25k's from home I drove home keeping it under 3000rpms.

If it is the bearing how good are the odds that I'm gonna need a rebuild? it was still driving fine when I got home? do you think It'll be right to just change bearings?

Cheers,

Russ

are you doing the work yourself or not ? If your paying someone to do it, once you have the engine out and open, it might be worth throwing forgies and a set of rods in there.. ($2k) since you're probably going to be paying that much in labour. Put a decent head gasket in there too.

in any case, if your not gonna replace parts, get them checked out thoroughly.. i'd say your crank will need machining at the least

Well your looking @ 1k for motor in/out before you start.

Then, if fitting new bearings your gonna have to machine everything to suit the 4 new ones you'll have to put in etc.

So 3k would be in the ball park as you cant really just swap one bearing, you do them all and freshen it all up.

You sure its a bearing?

pretty sure.. Its not something I have done before myself but a friend of mine done his in his silvia and said it sounds the same.. he's pretty in the know with these cars as he drifts and built his monstar, It seems to idle fine however if I give it a little rev it starts a knocking sound at 2-3rpms then clears up.. its a pretty loud knock very easy to here. and just sounds like it's coming from the head or front of the motor!

cheers

could be something in the head?

Im not up with whats inside SR heads, maybe a valve or something?

I thought a bearing knock didnt go away with RPM (as i did here a XR6t here and the knock only got louder with RPM), could well be wrong there

If you were giving it a good thrash just before it happened, its extremely highly likely its the bearings. Perhaps just look around on forums on here and boostcruising for someone who just wants to get rid of their sr, then all you have to do is take out the old one and put in the one you buy, then you have a whole motor sitting there for spares. I know my mate could have picked up a working ca for 150 im not sure on prices for the sr. But first thing you should do before you make any moves is get advice from a qualified mechanic and go from there.

i would get a professional to check it out before you start spending big cash.

Possibly a rocker arm. My ca was doing a similiar thing but it was the big end bearings gone. Soon after that i threw a rod. Go and get it checked from a mechanic. ust to be sure. I am not sure if the guys on here are right about the bearing noise would not go away as mine always did. As soon as i got over a certain rpm it wnt away. DR drift tunes a mates car and heard the same noise on a smaller scale up in darwin and then stopped tuning but he said it was a bearing knock and that goes away.

its alot more difficult to diagnose a engine noise in a full alloy block as the knock resinates through it.

best way to do it is to take load of cylinder by unplugging coil pack plug or injector harness one at a time. if noise lessens on a particular cylinder when you do this you can be pretty sure it is down stairs.

SRs are renound for this, usually because the sump has been pushed up and seals the oil pick-up. Look under the car and see if the sump is dinted.

I did a big end set in a GTIR last week, cost the guy $800. this included genuine bearings, synthetic oil & filter. Done it in the car. No probs. Only thing to check is that the crank isnt damaged. otherwise its engine out and full build.

where would that sound come from? mine seems to be coming from the top of the engine on the exhuast side!!! dam car only had it a week :blink:

The bearing noise would be there all the time man, there is no way that you feck a bearing and only hear it at a certain RPM.

i work with them all day lol.

Well actually, i KNOW from personal experience, that in my commodore (yes its not an sr) the big end bearings went on that, and before the motor died it made a knocking sound as you increased the revs and especially under load with the sound getting greater at heavier throttle. So yes, you do hear it at a certain rpm before the motor dies of course. The big end bearings can set your motors life short instantly, over very short time or could extend over a longer period of time depending on the severity of the damage to the bearings.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
