need help guys

Ok so recently I had a headgasket changed. I thought some white smoke occasionally afterwards always at low rpm vtec is fine. Also had oil leaking , turned out to the cam seal. Had popped out at the bottom and thats where the oil was leaking from.

So.. I dropped the car back in and had it corrected. Within 100 miles I had drove to work car fully warm, I stopped at Greggs as u do, and when I came out and started the car the idle was so low and rough and the exhaust was like an actual steam train. Temp was fine I decided to drag its ass the 30 seconds to my work. I got there and as I stopped hoses for coolant burst and car overheated, head gaasket is now blown again.

My mechanic picked up the car, said all the smoke was the coolant leaking onto hot exhaust I failed to agree. New hoses fitted, and again within 24 hours the same thing happened, hot engine turn off the engine then 5 min later a steam train exhaust. My idle is weird when ColeCold it jumps 1 to 2k sounds like distributer but I think not...

After extensive reading I conclude the intake manifold gasket has not been sealed correctly, acausing excessive air making the car run very lean. Also why idle is bad and smokes up to 4/5 k rpm as its far too much air.

I read that this excessive air gets caught and when engine is turned off the air works its way. Into thw coolant system and blocked the thermostat from opening which thus when I restart the car when hot it overheats.

I am 1600 Out of pocket right now and feel this all started due to my intake manifold not being not sealed correctly so can I pin this on my. Mechanic?

Would he have had the intake manifold off to get to cam seal right hand side of the engine or has it just been not sealed from headgasket job?

I done 1000 miles max before cam seal put back in correctly and 100 max after then the car was a steam train after restart.

What do you guys think?

Much appreciate the help I am going to see the guy on Friday. Sorry this is so long just wanted every detail in

Thanks

P.s mapped by Henry Roy within 100 miles of head gasket job. He didnt mention any worrys

so the steam from the exhaust was coming out of the tail pipe am i right and not from under the bonnet obviously until your coolant pipes burst?

Was the head skimmed each time it was removed and refitted?

Water in the oil or vice versa.

You do not have to remove the intake manifold to change the cam seal.

If the intake manifold gasket was leaking, you would have an erratic idle as the AICV would be trying to compensate the air leak post throttle body.

Steam was definitely out exhaust and thick

Head was skimmed 5 thou , it's had one head gasket change. Oil in coolant before and looks to be again

Idle is a bit erratic when Cold it revs from 1 to 2k itself then ssettles at 750 ish when warm

Thanks

Is it mis-firing by any chance?

 

[godfridge]

The 2 times when it has been fully hot, stopped switched off then restarted with lots of smoke yes and it idled low and rough at this point. Otherwise not that I noticed

Sounds very much like your having headgasket issues. Head has to come off IMO. The block needs to be checked for straightness along with cylinder head.
