Tel 0 Posted March 30, 2010 Report Share Posted March 30, 2010 Hi guys,recently done an engine change on my OBD1 VR. Started up today and runs lumpy as anything When the engine is under load it fills the whole street with smoke and on idle the revs are hunting like mad. I really can't understand it as when we started the car after the engine change it idled beautifully.I have checked all breathers, plugs, hoses, oil level, water level etc.Any ideas guys?Don't want to but if I can't solve it this week I will have to break it to get some money backCheers in advance Link to post Share on other sites
VR6Nat 9 Posted March 30, 2010 Report Share Posted March 30, 2010 Have you checked the ISV, it might need some cleaning... also have you run it with the maf unplugged to see if that affects it?? Link to post Share on other sites
Tel 0 Posted March 30, 2010 Author Report Share Posted March 30, 2010 I unplugged the MAF which made it bog down so I can rule that out. I'm sure the ISV is working, it came off of my original engine with no problems. Just a really weird problem Cheers Nat Link to post Share on other sites
craggsy 91 Posted March 30, 2010 Report Share Posted March 30, 2010 So when you unplugged the MAF it ran the same is how i read that Link to post Share on other sites

AJmk2 2 Posted March 30, 2010 Report Share Posted March 30, 2010 Possibly O2 sensor ? What colour is the smoke? Does it smell like its running rich ? Link to post Share on other sites
cabrioman 6 Posted March 30, 2010 Report Share Posted March 30, 2010 id be more worried about the smoke filling the street mate ..... wo colour is it does it smell of oil, coolant ??? Link to post Share on other sites
Tel 0 Posted March 30, 2010 Author Report Share Posted March 30, 2010 Smells of oil. It's white smoke. Worried it's a buggered bottom end that I have bought. Just seems weird that it was absolutely fine when we first started it after putting it in.Can't exactly go back to the guy I bough it from as I bought it 3 weeks ago and he lives 250 miles away.Not great Link to post Share on other sites
craggsy 91 Posted March 30, 2010 Report Share Posted March 30, 2010 White smoke to me is coolant/water...may be wrong.I work with white=water....black=fuel.....blue=oil Link to post Share on other sites
toadboy 0 Posted March 31, 2010 Report Share Posted March 31, 2010 check your coolant mate it sounds like the head gasket has failed thats a common problem of white smoke could have blew between a water way and its going out exhaust causin the smoke and smell Link to post Share on other sites
Tel 0 Posted March 31, 2010 Author Report Share Posted March 31, 2010 Thanks for the replies guys. The coolant has stayed at a decent level and not dropped at all while it had been running. I have checked in the cap but no moisture residue in there Link to post Share on other sites
