Lifters CA18

Since i did the rebuild on my sx and changed to the 8 port head the lifters have always been noisy.

Now they are going worse quickly, can i do damage to the car by driving it?

What are my options ?

First thing I'd say is strip, clean and rebuild/bleed them.

Then you can see how many are buggered, etc.

did you bleed the lifter before insert them?
or try to use thicker engine oil

I didnt build the head so dont know. been noisy since 2008 running the same oil, they get slighty better with thicker oil. just worrying me that they really noisy even from cold when the oil is thick they never just to be. Could there be an oil problem?

is it easy?

Don't just put thicker oil in, it only works for a short time and it such a cowboy way of doing things....I don't mean to step on anyones toes but it's no good, especially on a turbo charged engine.

Pull them out and bleed them properly or replace them. The head dissambley is easy enough and just replace the hydraulic lifters with new ones that have been bled properly

Hey rat
when i bought my sx i went past nissan and big bos auto they said i must put a special lifter oil in. i did that went quiet for awhile then i pulled them out to find it was my cams that wer warn. not saying its ur cams just saying have a look befor sumthing bad happens

The problem is where to get them if mine are stuffed. Thinking about maybe buying another head and going back to 4 port.

Anyone got that link on bleeding lifters?

To answer your question I find it very easy, just takes some time.

I added a link under the technical stickies a long time ago - that has pics and everything you need info wise.

Hi Rat

Check out Alert Engine Spares , I bought a set about a year and a half ago , paid approximately R900.00

Give them a call Part no. HL27 Stock number. HT60036AL , They have branches country wide

Hi Rat, sorry to hijack but do you or anyone else knows if the 200sx and 300zx lifters are the same? I think it was the RB25 that had the same lifters as the CA18....not sure. Anyone?

RB25 was very close and should work. No idea about the 300zx

Hi, just googled and a supplier of lifters in japan sell lifters and claim they fit the CA18, 300zx (z32),RB20/25. I will check this weekend as I have a few 300 lifters.

Hey Rat, Follow that link......I did and have just sorted the noisy lifter/s my sons sx has been having....it was quite a simple task, removed the cas and belt cover, loosened and removed the cam gears, removed the cam covers, removed the cam caps and cams. Removed the lifters and striped them cleaned them filled them with oil and pressed the inner bucket while releasing the oil by pushing the one way ball valve with a jewelers screw driver, then fit back into the main lifter assy, The rest is refitting and now we have a super quiet and smooth running motor. what a difference. By the way I replaced them with a set of used 300zx (z32) lifters I had spare and they are identical.

I also bought lifters from alert engine spares about a year ago, i called nissan for a price before buying mine and they wanted just under R1000 each, dont know what they were smoking

Has anyone had any issues with the lifters from Alert engine spares?? I have 1 noisy lifter that I need to replace but the agents want R800ea, not sure if I should change the full set of them to the Alert ones.

Rat, some advice from my side, I have seen this with my father in laws car, he also had noisy lifters, he sent it to a mack to replace, which they did, brand new, only to get after a few weeks that it started again, up and down...still had the noisy lifters. Freddy from the club had the same thing, also replaced lifters but had some that was still noisy.

After alot of advice everywhere, we decided to try this spec of advice, it worked, we flushed the engine with a half a leter of diesel fuel(add it to the oil) let it warm up...let it idle for 10 min or so, then replace the oil and oil filter.

I would recommend you check the oil pressure also, if your oil pressure is down, your lifters will also get noisy.

wow i posted this in 2010. I rebuilt my lifters the other day and they are much better. one or two need replacing
