The head should not be skimmed on the M51 diesel.Otto was doing the same but the heads were fine (got skimmed anyway), it was a blown gasket. Badly between 2 and 4 but also just a seep starting between 8 and the water passage.
As you say, only one way to know for sure and both need the same exploration.

True, but a new M51 head can be found for about €800 last time I looked.At least us V8 owners have a way out unlike the disposable M51 heads.
Just saying.

I wish i felt that way!! Bought the car with a duff engine.. had someone put a replacement engine in, that lasted next to no time.. third time unlucky!?At least us V8 owners have a way out unlike the disposable M51 heads.

Thought you were using electric fans?Dropped the oil and changed the fuel filter. Waiting for a new fan clutch and brake pads... The fan didn't fair so well after a swim the pads have however done four years and 50.000mls
Ay up Keith, I went back to the viscous, the fans for me felt to much too late as opposed to the viscous being ahead of the game. After the last radiator popped and nearly blinded me I've not had any other rad related issues since (although all aluminum now) . I did however manage to sell the mishimoto fan to a Mercedes w123 owner who was after a conversion. Win near winThought you were using electric fans?
Stat must have been badly adjusted, no problem with mine in these 40C temperatures and the engine is cooler when idling in queues when the viscous doesn't run very fast.Ay up Keith, I went back to the viscous, the fans for me felt to much too late as opposed to the viscous being ahead of the game.

I thought we stopped putting alcohol in the coolant years agoTook mine to the pub, very nice.

All 6 cylinders at about 300psi. That's a little disappointing. Further investigations planned for tomorrow.
Further testing reveals cylinder 5 is pushing all the coolant out. Stripped a load of stuff off but then one of the studs holding the turbo on sheared off. It would be the tricky f*cker at the back rather than the 2 easy ones. Anyway, had another job I had to do at 5 so packed in for the day. I'll have to take the head off later on in the week and see what horrors await.
Incidentally, an old compression guage has now been modified to attach to an airline to the glow-plug compression-tester adapter. Very useful although even on a slope and chocked with bricks in gear the car does tend to jump forward at you unless you ease the pressure up slowly.
