Rb2530 No Compression After Lifter Install

[BMYHOE]

Hey Guys,

so i pulled apart the hydraulic lifters for a clean as some were very noisey.

i basically followed this - http://www.gtrpwr.com/showthread.php?t=726 except i cleaned them individualy and left the lifters sumerged in motul 6100 15w50 oil for 48 hours, then put the lifters back into the spots they come from.

now after installing everything and checking timing about 5 times i have no compression in any cylinders..

if it possible that i have blead the lifters to much or am i missing something here?

Are u 100% sure u timed it right the first time? Hopefully u havent bent the valves.

Check the valve clearances

[BMYHOE]

I have checked 5 times and had anther person over to confrim the timing is right...

the more i read around the different forums, some are saying to not pre prime the lifter before assembly, to let them prime once in the head?

That guide is correct way to do it, ive done a few sets exact like that with no problems. If you followed it then lifters shouldnt be the problem but hopefully its not the timing or else going to have some mashed valves.

Im hoping that smashed valves are not the case!

anywho going to be a fun night tonight

i had a similar problem, poured a little bit of fresh oil into all the lifters before putting them back together and 1 ended up having too much and refused to bleed down, causing no compression on that cylinder. pulled it all apart and replaced the lifter with a spare and problem solved

i managed to figure out wtf i did wrong..

very stupit mistake.. when i was assembling the lifter bodies i managed to put them the wrong way around which is why they could no bleed down.. i i didnt put the check vavle side into the lifter body, but the other way around.

we dont believe it has done any valve damage but will know more later today

Shouldnt have valve damage if timing was right and that was your only problem.

yes well that is great news, that was def the problem.

in the process of fixing my f up lol

I havent cleaned mine as they were already clean, not knowing any better i hit them with compressed air and blew the old oil out after a soak in petrol. I hope I havent damaged them? a few were pumped up by air, will this bleed out or is this bad? engine not started yet. Any info would be good thanks

Bleeding air/oil out of lifters;

Pull lifters out of buckets, push a pin/ paper clip into the ball bearing part, afterwards it should compressby gently squeezing it, if it doesn't, it either has oil or air still in it

Leave in oil over night or put in and crank motor until you get oil pressure then start the car

[abr33]

Ok cheers mate, will the fact that a few are pumped up with like 100+psi of air make the valve ride and hit pistons or nothing like thats possible?

[BMYHOE]

all fixed now

Excellent.
