Hi all

got a quick question. My drive is fairly steep, and when parked over night, and i got to start the car, the tappets tap for possibly 10-20 seconds if that. Possibly happens 1 out of 30 starts.

Now this doesn't always happen, and appears to be radom, sometimes it does other times not at all.

So does this couse s hit load of damage, i am goign to get some lifter free treatment and hcange my oil, to see if it helps. I know it has to do with the oil pickup ect ect, i juts wanted to ask, if it is going to couse damage?

Mine does this too. Its only for about half a second.

You could always try to get it level before you start it. I park on a hill every night but roll back a few metres onto level ground to start it.

My old pulsar did it too.

well it still doe sit, especially if parked on a funny angle on a hill with the front nose up, but it stops within 5 seconds if that, and the oil pressur eis all good, did a test, bypassing the stock selenoid, and the oil pressure is exactly as it should be as per the manual.

I'm doind a service soon, goign to get some engine flush and tappet free treatment, and see if that improves it a bit.

The RB26 uses solid lifters so they will always be harsh and quite noisy. The only way to quiten them down is to re-shim them. I think the RB25 uses hydraulic lifters so if they arent supplied with the correct oil or not enough they will not do their job correctly and you get extra noise from them.

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
