thanks for your advice, will do my best to do those tests but i found one small vacuum hose disconnected at the back and and i reconnected it and the car is a lot better at idle but when coming to a stop or reversing the car judders and is about to stall,is driving rough and less power and also low rev at idle and the car any clues as to what could be causing this issue?

ironheart:
Did u align the ring n oil seals properly? I have read that they all have to face different angles. Also, you need to cut/grind the engine block, so that its become round again. The new rings are circular while the block is oval due to the old rings, this may have been the reason for your premature engine failure.

Thanks so much for taking the time to reply, however the fact is I am not an expert but I have done my best to follow the book and what the professionals do and say in regards to rebuilding an engine, and yes I did align the piston rings correctly because I knew that this will be important to keep the chambers stayed sealed all the time.

I have torqued each and every bolt according to the manufacturer's repair manual.

But my question is what you fellows think is causing this slight misfire and white/grey smoke that is blown out of the exhaust pipe when cold starting the car.

Thanks

Thanks anyway.

Hi Everyone

I would like to post my issue here and this is my first time I post threads on this forum and hopefully I get some help from you members.

My issue is that I have just rebuilt a 2004 Toyota Voxy engine (Engine Code: 1AZ-FSE) 2.0L Petrol Automatic and am having the following problems with the car when I start it:

1/ Car rev too high (2000RPM) on start up
2/ Car starts blowing lots of white/grey smoke on cold start and clears away after running for 2-3 minutes and also when I put My hand in the smoke it feels a little bit greasy.
3/ Car also has got some misfire that can be felt when listening to the exhaust pipe blowing intermittently.
4/ The engine gets really hot real quick and the fan keeps coming on very frequently but I think this might be due to some air blockage in the cooling system or some leak in the radiator.
5/ The oil dipstick kind of smells of petrol.
6/ No fault codes given when scanned with my Autel MaxiSys Pro MS908P.

So my questions to the experts here are:

Do you think this is an injector leak issue? or a Vacuum leak because I suspect some bad intake manifold gaskets?
The engine sound is smooth and all the valve stem seals, piston rings, con rod bearings, head gasket and timing chain replaced and the crack shaft was regrinded by professionals in the rebuild process . And also the engine was thoroughly cleaned before assembling it.

Your quick replies will be highly appreciated as I am really not sure where to start with fixing this engine.

Thanks.
