gday

i have an r32 with an RB20DET and i have been having some trouble with my enging and to much pressure in the bottom of the engine.

i start the car up no smoke rev it to 3 or 4 grand and blows heaps of smoke like clouds of the shit,

i have done a compression test and it came back with 120psi accross all 6 cylenders.

i pulled the breathers off that go to the rocker covers and reved the same no oil untill i snap off the acceleraitor and then everything gets covered it had a habbit of blowing out the dipstick which im guessing is the same issue of to much pressure, i have replaced the pvc valve and no change.....

and im running out of options does any 1 know what the issue could be??

im thinking it could be either a cracked piston or maybe rooted rings...

it still runs well and goes pretty hard exept for the smoke......

thanks Blackrz

hey blackas sysmptoms sound the same as my engine was in its early stages of its death, mine was lower on compression in 2 of the cylinders tho, when the engine was stripped for rebuild, lowest cylinders had the sides burnt 0ut of the piston the others cracked rings, get it check by sumone who knows what they are on about. think you pressurise the sump and do the reverse of the compression test to find out if its blowing back through or sumthing like that. any way good luck or maybe time for a 25

if you get the chance drop into pro automotive in moonah and ask andrew to have a look - it will take 15 mins of your day and he will give it to you straight, no bullshit and then there wont be anymore guessing and wondering about it - he will tell you whats wrong and what needs to be done from here to get it peaking again :P

This might be off the money but my mate had the same problem (exact) with his car. Would not blow smoke till high in the rev range and he did blow his dip stick clean out of its home. Turned out to be a seal in the turbo going and it pressurized the oil feed line back through to the crank case and blew the dip stick out. Just a thought....

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
