Hey. I just got my r33 gts-t back on the road. Redid the timing and she was running sweet. Had the timing fairly well advanced, and the car had lag issues before but the advanced timing via the cas fixed that. Went and did donuts and holding just below 7k and I have a feeling the radiator had not much liquid in it and it seemed to be overheating. After I finished spinning and pulled out from the burnout the car stalled. After I got the car started it seemed to idle alright, but there was a strange knocking noise and it seemed to be coming from the rear cylinder. So I got the car toed and haven't bothered to run it because I am afraid I might hurt the car.

It had been blowing white smoke too.

Does anyone know what could be causing it and or how to fix it?

Much thanks in advanced.

Matt.

In my experience with other older types of cars (not imports or nissans but hey an engines an engine right??) white smoke usually means water getting int o a cylinder from a f**ked gasket or cracked head hopefully just head gasket try letting it idle with radiator full and look for bubbles, if u get them then gasket. Theres another way where u use a compressor thru the spark plug holes and also watch radiator but Im not 100% on that one

Was there water in it in the end??

It only seems to tap on idle, when the revs picked up it goes away I think. Could injectors cause this? higher fuel pressure at higher rpm masking the potential problem with the injectors?

@AaronNM35

Pretty sure it's stock so it would be tappets. thanks for the feedback :)

@rickr333

There was coolant in it, I had to dump it when we were looking at the engine. Thanks :)

Oh a loose conrod, that's not right...your engine timing must have been slightly out...can't think of any other cause. Tell your engine rebuilder to use a left handed torque wrench when he's torquing up the end caps...RB engines respond to them more positively than conventional torque wrenches...a lot of rebuilders don't know this.

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
