Oh no... all done and running now.

[zaust]

Mayo on the oil cap and a little on the top of the dip stick. Looks like a head gasket as I have already had the cover off and run it up, there's no signs of cracks or jets of water.
Just need the time to do it now. .

[Rav335uk]

YOu'll sort that out no problems Marc.

Has the car been standing?? could be moisture, seen this on Clio's

[zaust]

No not been standing, gets abused weekly. Supprised it lastedthis long. Still runs fine too. But 250k ain't bad going.

[Rav335uk]

You still got your spare Head???

[zaust]

Yep, thats ready To bolt straight on, will get a head set ordered up tomorrow. kinda glad you didn't buy it now lol.

[Rav335uk]

I knew you'd need it later,

[zaust]

at least the evenings are lighter now.

[leeparkes]

Bad news! but in a way good news if you have a spare head.

[zaust]

True but still pants.
Well I can recon the head that comes off and sell that if it checks out ok.

[zaust]

Going to do all the normal tests on Sunday so I know wher to look when I take the head off. I don't suspect block as she's not pressuring. Fingers crossed or new lump hunting.

I can get my hands on a E28 b34 and bolt my bits on but not sure its got the same pull.

[leeparkes]

Im sure earlier e28 engines are higher comp

[zaust]

Yes but smaller valves.

[Rav335uk]

B34 has a spikey cam too

[Speedtouch]

I'd wait until warmer weather - it may disappear then, of it's own accord.

[zaust]

I very much doubt that mo, besides its nice and sunny here.

Rav something tells me to stay away from the e28 lumps.

[Rav335uk]

E28 lumps , if you get one for the right price, aren't too bad mark, but many are past their own sell by dates, and ideally need a few £'s thrown at them.

E34 are better, peado pete has one if you do get stuck looking for a good one.

[zaust]

do you know how much he wants ?

[Rav335uk]

No. didn't ask him

[zaust]

Will have a chat with him, thanks for the heads up.

[Rav335uk]

[zaust]

Well put pressure in each cylinder and got good results. So not head gasket. Pressurized the water system and with two people searching the little dribble was found. I took a pic will post later. So as its a cracked head I can order a head set and get on with changing it with the spare head.

[Speedtouch]

So M30 heads crack as well? I thought this was an M20 thing.

[zaust]

All 12v BMW heads have been known to do so. And normally around 5 or 6. Mines gone on 5. Its a shame as the rings and valve seats are letting very little pressure through on 2 & 3 and the rest are fine. Will put it down to using the nos to much and stressing it before its time.

[Rav335uk]

I thought the heads were stronger on the M30, taking about 400hp without any failings

[zaust]

[zaust]

some progress

[Rav335uk]

So, what was it then???
And clean the front end of the engine too

[zaust]

Its a cracked head nothing else. Order new gasket and bolts and fit the other head.

[Rav335uk]

Up and running by the weekend then??
You skimming the head Marc?
Like Gareths?

[zaust]

All done and ready to go. Won't have a day off for a while now, but soon soon.

[leeparkes]

Lift it into pos 3 while your there.

[zaust]

Won't get the head on if I do that first. Also easier to put it on with the inlet manifold fitted.

[zaust]

Standered thickness elring head set and bolts turned up today. will be fitting next Sunday or Monday now:( not enough time left today.

[zaust]

Started on the button few bits to bolt back on and then some run in time.

[Rav335uk]

Done yet Marc??

And pm'd mate.
