Whats up, I recently just rebuilt my RB2.4 kit engine and when my HKS 264 cams for both intake and exhaust where installed they where installed at stock setting by the RB2.0 service manual. Now when I cranked my engine my car was making a tapping noise from the head, almost like the valve where hitting something or some of the hydraulic lifters went bad. Now the thing about this head is it was already on my RB2.4 engine before and the only thing that was taking out of the head was just the cams, all the rest of the internals of the head stayed inside (ex. valves, springs...) Now if my HKS 264 cams where set at stock settings do you think it would cause my valves to hit something? If so do you think it would cause any damage for about 10mins worth of running all together. Also I looked up my cams and I saw my cams should be set at 110 degrees for the intake and 115 for exhaust and stock settings are 0 degrees. Soooo do you think the stock settings would cause my valves to hit something? Any help would be appreciated... Thanks

JOnJOn.

I'm pretty sure that the stock RB20 head/block are non-interferance, so the valves won't hit the pistons. BUT if you've changed the stroke - which you would to get the 2.4 - it'd be different.

Might be time to take the head off again :P

ouch... that's a shitload for cam gears... i thought they were about $220 each, or am i looking at shit brand?

I've got an RB25DE Non Turbo head to go on my 3lt block. What cams come in them? they are less then 256's aren't they? but a bit more aggressive than the RB25DET?

toda can be purchased ex jap new for around $220 each. You pay $600 odd when you purchase through the australian sales channel.

Until the local peformance parts retailers organise themselves properly and setup distribution channels just buy overseas, it's cheaper and quite often faster.

TODA AU - perhaps you should pull your head in. Many people import directly from Japan for the exact reasons rev stated. Customs dont hit gst or duty for private imports (not talking about quantity).

that aside - who the hell do you think you are? thought police? this forum is hear to share information, not slag off at people. You have just destroyed your credibility in my, and I am quite sure many other poeple's eyes. You have a go at sydneykid for no other reason it appears than to try and progress your own image. then you decide to start doing the same to others that are voicing an opinion - thats what this forum is for, if you dont like it perhaps you can take your attitude somewhere else that it may be appreciated.

As for meeting up with rev - I'd pay to see that, usually the smallest dog that barks the loudest.

I have no doubt you will have nothing but more abuse for me - but hey, I have to respect you before its likely to worry my so fire away if it will make you feel better.

      Blue/grey smoke after idle

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.

      The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
