INSANE M42 Engine Problem
« on: May 27, 2015, 03:35:37 AM »
I dont know what to do anymore!
PLEASE HELP ME

Problem:
My M42 had some engine issues, it wont idle after starting it up when engine is warm - but i think i solved this problem.
BUT it smoked white after coldstart in the morning and needed some water... It starts not proberly, the starter can not be cranked, i need to try it 2- 3 times, after it starts it runs on 3 cylinders.
We thougt, okay - headgasket

We renewed: head gasket, head bolts, thermostat gasket, all gaskets from cylinder head, all liquids, aso...

Problem NOW:
It smokes white after coldstart in the morning and has all the problems like before, will not start, runs on 3 cylinders aso.... !!!  :'( :'( :'( :'( :'( :'( :'(

BUT (and now it comes)
It smokes just if it stands horizontal or uphill (in direction of travel)
If it stands downhill in direction of travel IT STARTS PERFECT, RUNS PERFECT, NO SMOKE

COULD SOMEONE PLEASE HELP ME!!!!! I´M GOING MAD!

Autotec,

:( Could very well be a crack in the head near any of the coolant passages or even near the head bolt holes.

If you replaced all those things and you get the same symptoms, I would suggest taking the head off again and having it checked by a shop for cracks..

Sorry but that's what I would do.

Good Luck.

Cheers,
~Ralph

The head was in a workshop, they planned it. We controlled it on cracks before and after!
Nothing...

Its a mystery to me... if it stands the whole night downwards nothing, upwards white smoke aso...

Autotec.at,

White smoke is coolant in your combustion chamber.

Is the head gasket a stock gasket or cometic?
