Startup up my R33 this morning, and noticed small amount of white smoke coming from the exhaust. Almost looked exactly like condensation, but to be safe, I drove it into the shed and started to dismantle. Took the intercooler piping off. Found oil Took the cam cover breather pipes off. Found oil So I cleaned out what I could, put it all back together to drive down the road to a garage. Started the car to make sure I put everything back together right, then smoke started filling up the shed. It was coming from the exhaust/turbo side. So I thought blown exhaust gasket. Then realised the oily mess I found before, could of been coming from the turbo and the smoke I can see is it burning. So I removed the o2 sensor to take a quick peek for any traces of oil. As soon as I took it off, white smoke started coming out if the hole. Not much, but looked similar to the steam you get when a kettles finished boiling. So my question is, does this indicate that my turbo seals have blown? Or could it be that oil is being pushed through the cam cover breathers going into the intake? Im really hoping the seals on the piston havent blown

Ok cheers guys Ill get him to take a look near the gearbox. I did notice a small machined surface close the the gearbox, but it was covered in dirt and crap so thats probably why we didnt notice anything. It is turbo with greddy intake to solve bonnet clearance which is why we thing the rb30 is in it, and has the heatshield over the exhaust manifold so we cant see anything unless we take it off. The guy he bought it off had no idea about cars, so was only going off what the previous owner had told him. Apparently there was an rb30 in it, or maybe still is. When he bought it it had a fairly beefy fuel system, custom exhaust and intercooler piping. and thats a bit extreme for a "stock rb25" as the guy thought it was. Seems a bit odd that the previous owner would take the rb30 out, put a 25 in, and fabricate custom piping for it? Unless he blew it up or something

Ok, sorry for such a n00b basic question, but I couldnt figure this for the life of me. Is there a way to identify an RB30 block without actually removing the engine from the car? Mate just bought an R32 and has suspicions that theres an RB30 block under the 25 head. Is there a code or something that we can look for? Ive had a look around and all Ive found is 75T written on the passenger side. Any help is much appreciated guys

Cheers boostn thats what I was looking for. Much more simpler that what I thought. But looks like its gong to be a long job

thanks guys. I've already flushed the engine about a week ago, so I'll add a bottle of tune up to see if it helps.

Ok so im hearing that annoying ticking sound coming form my engine and its driving me mad becuase its noticable from outside the car. I was going to replace all the lifters because I know one is at fault, but before I do, I thought I might have a crack at cleaning them. So, my question is, how do I remove them? Ive never done anything like this before, so I have no idea how Id go about getting them out. Anyone got a small step-by-step guide on how to get them out? Another thing I should probably ask is once I do eventually take them out and clean them, do I need to adjust anything or can I just put them back in? Cheers guys

I hope its as simple as a blockage and hopefully will go away its doing my head in Ive taken note of the pressure level at each rpm and it seems to go way out of wack. Another thread on here stated its suposed to be: 14psi @ idle 50psi @ 2000 rpm 80psi @ 6000 rpm Now, im getting: just above 20 psi @ idle 60psi @ 2000 80psi @3000 This is all when the engine is warm by the way. Thats a hell of a difference! Im too scared to take it over 3000 rpm in case something blows out. Im so cinfused as to what could be causing this. And Moodles, i dont think he put chemiweld in it, because the stuff costed like $170 compared to the $10 chemiweld thanks for the help so far guys!

I know its been a while since i last posted, but i just cant seem to pix the issue!! Ive replaced the oil, with a nice 10w40. I also pulled the intake pipe off from the turbo and found a bit of oil in it which i thought would mean a bad pcv valve. So, i pulled the pcv valve off and gave it a clean. You could hear the ball rattling around inside which ive heard is a good sign and i could blow through it one way and not the other. Took it to a mate who is a mechanic and he put some stuff in the radiator which he said should "fix" the headgasket, if it was the headgasket. Well, whatever it was the car no longer has water/steam and white smoke coming from the exhaust so thats a good sign. Im still confused as to what would make my oil presure so high?? and the car still idles a bit bad for the first 5 mins on startup. Im thinking it could be a bad oil pump? or pressure relief valve?

ok thats the first thing ill do tomorow then So, best oil to use. Royal purple? Or would a 10w40 from the local auto shop do just fine?

I didnt put that oil in there the guy who had it before my did. thats why i wasnt 100% sure what it is. Do you reckon thats the cause of the high oil pressure? I was having a read around and found that it may be caused by a blockage or someting. like a clogged oil filter? I took some videos today of the guage when i first started it, and also what its like after a 20 min drive, where i was driving like a grandma. If someone knows how i could do it, i can post up the vids as it probably explains it better then words cheers for the help so far though!

So its fine to go past 100psi while driving cold until it warms up?

pretty sure is valvoline xld 20w50

Hi guys, Im new to this forum, so hopefully ive posted this in the right place I own a 1993 r33, and the other night I was on a cruise with a few mates. Didnt do anything stupid, just boosted it a couple of times. And everything was fine and dandy. but the next morning when I started the car, some white smoke started coming out the exhaust. it was noticable from the rear view mirror. So i got out and had a look and either put it down to condensation, or a blow head gasket :S In the afternoon i had to go down the road to pick up some things, and was worried about this white smoke. Started the car, no smoke. When i got to where i was going i got out and checked again to see the smoke and there was hardly any at all. Got back in the car and drove home and havent seen any white smoke since. but when i started it the idle was kind of lumpy. On the way home though i noticed the oil pressure guage and the oil pressure was going between 80-100 psi! (the guage only goes to 100) After a while it did drop down to 50-70psi though, but took a good 10-15 mins of driving for it to do so. Is this normal for these kind of engines? What oil pressure should i be running at? It never did this before and its got me confused and worried. But yet the car seems to be running perfectly fine otherwise :S Any help is much appreciated!!
