Stills sounds like a HG but it could be an injector problem. When you say it smells like oil, do you mean diesel?

Was the head gasket OEM or a cheapo like sitpart for example?

hi the head gasket was origenal bmw one befor i changed the head gasket the car was overheating and there was oil coming out of the exhaust .when i took the head of number 6 piston was wet with oil i thort the valv stem oilseal had gone

Turbo oil seals, was the head checked for flatness ?

Mike v.t.s · Jan 29, 2011

Is it not a crack in the head or even the block itself?? hope its not but if i was you id be checking

Sounds like a timing issue if not a compression issue.. Had similar on a 300tdi before with white smoke. White smoke means you are not burning the fuel at the right time.

thanks for thee reply is there any wy to check the timing

One cylinder with oil in it. Don't think turbo oil seals are quite that decerning in their distribution.

You cannot do pump timing without special tools.

The white smoke could be residual oil left in the exhaust being burnt off.

As for running lumpy, bearing in mind the engine has hydraulic tappets did you collapse the followers (if your using the original ones) before rebuilding the engine and has the engine run long enough to re-adjust them?

If he didn't he has several valves attached to pistons.

markowl · Jan 30, 2011

i there look at the injectors today and all look ok so it must be the timing so gowing to look for a for a diesel speshelist in my area and get a price on dowing the timing for me

markowl · Jan 31, 2011

i all looked at the car today found one of the connectors wasnt connected rite on the inlet manifold so check all the other ones. now the car ticks over perfect but still geting blue smoke out of exhuast i think the injector timing might be out
