Ok, take some pictures, we need picture of the head inside to tell if there is some difference to 3TB. Dont know what bolts you talk about, change the seals when its open.

Number 14 from here.These are the bolts

Explains the low compression, did you or the mechanic pull the bolts with correct torque?

Mechanic..

And that's why i think was the smoke .

I guarantee the "mechanic" knew those bolts were stripped and just snugged'em up good enough then let them go.

What happend here, "mechanic" still alive??:mchappy:

The mechanic it's ok :blushing: . I order new OEM bolts and i think at the end of next week they will arrive. I think and hope the problem with smoke it was from this torn and another one worn bolt. Rings,valves are ok,in good condition.

I'll be back with news after i finish to reassembled the engine. Thanks for everything! bierbier

Ok good look, lets hope he finds the torque wrench this time:clap:

:mchappy:bier

Hello guys, I mounted the new bolts. Same problem. Rings are OK,I did a test leak at cylinder head,OK. :( I don't know what to do..maybe replace the valve seals?

Well you shoud have done it when you already had head off..Why dont you just ride and enjoy summer, check oil consumption and change seals in the winter if its necessary:thumbup1:

BTW my acer have smoke when its cold outside like 5Celsius but there is no smoke when its 16C.

that's it for this summer. bier Just ride.
