DREMEN Posted May 18, 2003 Share Posted May 18, 2003 OK I accelerate as normal.......... hits 3000rpm and starts to boost a little, then it sounds like a hair dryer in the bloody engine bay! It just sounds like its blowing! And the car is very sluggish on boost.... Now my first thought was boost leak.... checked it all over and it seems to be fine.... all hoses attached and the blowing is so loud that it wouldn't be a tiny split or hole in the hosing... So I thought maybe the bov (trust plumback) had farked up. Just changed it over and still the same problem. I did however notice a fair bit of oil inside the bov. So now I am stuck for ideas!

hawks Posted May 18, 2003 Share Posted May 18, 2003 dude, sounds terminal (maybe you have farked the turbo/snapped exhaust wheel off) also, there should not be any oil inside your bov take it to a mechanic good luck good luck Link to comment https://www.sau.com.au/forums/topic/16204-please-help-problem-with-my-skyline/#findComment-331763 Share on other sites More sharing options...
DREMEN Posted May 18, 2003 Author Share Posted May 18, 2003 Just talking to a mechanic at croydon...... he said that oil in the bov is normal for the RB...... its not much........ just a little bit... maybe you have farked the turbo/snapped exhaust wheel off If it was this then why is there boost leak noise?

hawks Posted May 18, 2003 Share Posted May 18, 2003 yeah a little bit is normal with any pcv system. when i had my gti swift turboed, i snapped the exhaust wheel off, and it sounded like a jet after certain revs. simillar to what you explained about yours.

DREMEN Posted May 19, 2003 Author Share Posted May 19, 2003 I have found a stud is broken off the exhaust manifold... Could this be the cause?

MotoX Posted May 19, 2003 Share Posted May 19, 2003 yes. when u say jet, is the noise wooshing or like a chinsaw. a nut come off my manifold/turboflange. blew the metal gasket. got a new nut, new gasket $37. boost came back up. car stoped making shit noises.

DREMEN Posted May 19, 2003 Author Share Posted May 19, 2003 like a wooshing noise.... yeah the stud is broken so I will have to get that fixed.... Might have blown the gasket out Link to comment https://www.sau.com.au/forums/topic/16204-please-help-problem-with-my-skyline/#findComment-333645 Share on other sites More sharing options...
adam 32 Posted May 19, 2003 Share Posted May 19, 2003 you shouldnt loose that much power but sounds more like a leak than a breakage. check for moisture around any of the exhaust gasket areas, make sure no intercooler pipes have blown off and that theres no boost leaks (which youve already done) is it definately an air-rushing sound and not a mechanical sound? that would be the decider!

DREMEN Posted May 20, 2003 Author Share Posted May 20, 2003 I am almost positive it is an air rushing sound..... I am taking it to an exhaust place now for them to look at the stud Link to comment https://www.sau.com.au/forums/topic/16204-please-help-problem-with-my-skyline/#findComment-334757 Share on other sites More sharing options...
DREMEN Posted May 21, 2003 Author Share Posted May 21, 2003 They reckon that its not the stud...... the guy said he has only ever seen 3 skylines with all studs intact So now I have it booked in to have a smoke test done.... There has to be a boost leak somewhere but I just can't find it I want my baby fixed Link to comment https://www.sau.com.au/forums/topic/16204-please-help-problem-with-my-skyline/#findComment-337525 Share on other sites More sharing options...

There has to be a boost leak somewhere but I just can't find it I want my baby fixed :( Sorry for dredging up slightly dead topics but my R33 has a broken exhaust manifold stud as well. Did they give you a price on fixing it? Ive been told $1000. But i brush that off as them taking me for a sucker, they said they wanted to "do them all at the same time" which i took to mean "we want to take all your money at the same time". Im a bit interested to know that this is a common skyline problem. Has anyone ever fixed this before?

YBSLO4 Posted June 23, 2003 Share Posted June 23, 2003 They would have been right dude. If you have broken one off, which means you have the bolt stuck in the thread of the block, then it has to be drilled out and re-tapped. Tricky and time consuming hence costing money, and ya guaranteed to snap at least another getting them off. Ya gotta remember also to get the manifold off, you need to remove all the intake piping, the turbo, the manifold etc. then ya gotta take the block out... not a small job.

Yeah, thinking about it, there is a lot of labour. Does a broken stud mean it will be leaking exhaust gases? Perhaps not since im only running stock boost. I dont hear any leak noises or feel any power loss, but its always been broken so i may not notice it.

51jay Posted June 23, 2003 Share Posted June 23, 2003 With the manifold removed you should be able to get at the studs with a drill and easyout without taking the engine out. If I had to drill them right out I would use inserts rather than just retap the holes to a larger size. None of mine have broken yet, do you guys use a torque wrench??

DAMQIK GTS-T Posted June 23, 2003 Share Posted June 23, 2003 DREMEN Do yo get a boost reading on your boost gauge? Check that the top half of your inlet is bolted down properly I had a boost leak from there once. also with the broken exhaust stud I also have one broken but not leaking (broken before I got the car) and I've been running 14 psi for about 2 years now.

Drivebai Posted June 24, 2003 Share Posted June 24, 2003 i thought air rushing sound was normal esp if you got a pod filter.. all the skylines i've seen driving round you can hear the air rushing.

YBSLO4 Posted June 24, 2003 Share Posted June 24, 2003 abroken stud wont cause an exhaust leak unless you have some seriously big exhaust flow. You gotta remember there is two studs for each outlet so there is a small chance of it being able to leak as there is still one bolt holding that onlet in place, as well as the strength through the other 10 bolts on the othre 5 exhaust outlets. I have a broken stud on mine it broke last week when fitting my turbo and is the reason why after i took that one off (luckily was first bolt closest to radiator) that i changed plans and removed the turbo without taking off the manifold. Be careful with them, they come out easy but once you bolt them back in they are rediculous, they snap before you even get an load on the bolt. Definately replace them if you ever take them out.

GILTY Posted June 24, 2003 Share Posted June 24, 2003 I drove my R32 over a gate magnet on an industrial driveway and ruptured my engine to manifold, manifold to turbo gaskets and 2 other smaller gaskets down the exhaust line... I took it to an exhaust shop and was quoted over a grand to fix it because of the labour involved... I said shove your grand up your azz! I have 2 good mates from Cyber Motorsports int and they have access to full workshops, therefore, we spent a weekend (about 24 hrs total) removing my turbo and all ancillary stuff, refitting new gaskets and putting it all back together after a general clean up etc. Gaskets can be bought from Nissan Aust in Brisbane, at about $106 for the engine to manifold, and $30 ish for the other 2 (manif>turbo and turbo>dump) so $180 ish for all 3 (not bad really). You need an air drill to drill in the middle of the studs (I had 5 broken off in the head) and the easy out is a must. I was extreemly lucky that all my studs came out in one piece otherwise the head comes off and "rebuild" enters the equation.(nasty $$$) I must say that I thoroughly enjoyed the experience as I now know exactky what goes on under there (respect maybe, but I still thrash it). PM me for any finer details as I know everything first hand. The help I had made it all possible, so make some friends with workshop connections and it will be all good!
