Changed The Head Gasket-way Down On Power :(

[Anton green 12 1 Cars]

After getting the head gasket sorted on my 205 it is down on power, and I cant see why.

Today I removed the cambelt cover and checked that the pins line up and that the crank is in the correct position too and it seems to align. Also checked the downpipe for dents or creasing where it recently fell off a car-dolly to the ground a few centimeters and may have damaged it when it landed - but nothing too serious there either.

 

Then I checked around the manifold and saw the odd bit of smoke mist when the engine is revving, but could this be due to exhaust paste drying out and steaming-off or do I definitly have a leak there? and would this lead to a drastic decrease in engine power (along with the car sounding a bit tank like)?

 

Cheers all

Might well be exhaust paste drying out, but that wouldn't take that long. You could get someone to hold a rag closely over the end of the exhaust & see if anything leaks then. Unlikely that would cause much loss of power though. Suggest you check all wiring correctly connected, plug leads in correct order, ignition timing correctly set. If you've had head skimmed, you will need to advance ignition beyond original setting.

i would compresion test it and see what that turns up,

Yup, just got back in from Derbyshire's finest back lanes, the car seems gutless at the top end of the rev range. To adjust the timing after the head skim, should it just be a case of altering the distributor position (full 405 Mi16 loom)?

 

And if so, will the amount of rotation which the distributor needs be within the amount of travel which the distributor has when its bolts are slackened off?

is this a mi16 or 8v?

is this a mi16 or 8v?

 

What he means is there is no adjustment on an Mi16 distributor - 8valve dizzy with adaptor yes. I suspect that bump's had an adverse effect somewhere.

you may, if you have skimmed the head taken it may be beyond its limit, are you getting steady white smoke or intermittant?

i normally find a blowing manifold saps all you're power . hills really suck when you're manifold is leaking . depending on where its leaking it usually just sounds like a noisy top end rather than a car with a burst exhaust

Yeah, if its an 8 valve check your ignition timing, but also do a quick compression test to see if theres any errors.

 

Burning gasket/oil should go within 10 minutes though of running!

 

You wouldn't of happened to of put your exhaust manifold gaskets on wrong, and basically making that restrict the head? Seen that done before.

 

Easy to check aswell, by just removing the manifold.

Nope, as far as I know - got someone else to bolt the head up.

 

Its an Mi16 which has just had its head gasket replaced in a 205GTI. I cannot think what it is doing wrong - apart from not going like it should.

Everything has been done the expeerts way AFAIK!
