Hey guys,

I've got a 1996 r33 skylines series 2 purchased the car about 2 months ago now and nothing but grief from the start, coilpacks went so I changed to splitfires replaced plugs to iridiums, then it was running sweet for a while then my clutch went and now my current problem... When giving enough acceleration to boost, when spooling up you can hear this strong clicking sound coming from the engine bay, you can hear it very faintly on idle but really only when I'm boosting, if I lay off the boost you can hear the clicking very faintly but hardly noticeable, anyways I suspect it's definitely turbo related maybe the turbo is on the way out? Or maybe a gasket has completely worn or something is loose? I've had a look at a few things, first I thought it mite have been my aftermarket boost controller solenoid clicking so I removed that and still no fix, took the heat shield off the turbo and the dump pipe doesn't look in great shape and it only has 2 out of 4 bolts on it.. Turbo definitely isn't completely gone as I'm still making boost and haven't really seen much performance loss.. I was thinking maybe a damaged turbine blade but those things doin at like 14rpm so it would have shattered by now. Currently bidding on a turbo on eBay anyways to have one there if it is going to go.. But what's ur thoughts guys??

Looks like the link above with same story 2 studs missing... is it an easy job to replace studs and gasket seems easy enuff? undo bolts put new gasket in and tighten or am I missing something?

cheers dudes

I'd be looking at the exhaust manifold gasket, going from the symptoms you mention.

A tick, tick, tick type noise "usually" means just a single exhaust leak per power stroke whereas at the actual turbo gasket, the explosions have blended into a fairly solid blast of gas.

Remove the heat shields and have a good look at the junction between exhaust manifold and head.

Look for signs of carbon even sometimes a slight oil weep.

Don't forget each exhaust port has 2-bolts, very often the exhaust manifold studs snap off.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
