Something went bang...

Alex sorry to hear of your woes, keep your pecker up old chap.

Another suggestion for what it's worth, rather than chasing round the world for a 55k engine, why not buy a complete car from a breaker ?

 

[ajlsl600]

I may do this after the refund is processed, I would normally chase them but this is number 6 on a list of stupid stuff happening to me this month (including trying to buy a house, moving, blown up car, other car blown up, stupid neighbours threatening family etc), so its been pushed down the list.

alex sorrio,hope all sorts out well,if i was nearer would come and offer some help , considered fairly useful with eng/trannies. crap with electronics tho. thought my day was bad got up ,pc on, find document ,select print ,nowt! 2 hr later faulty usb cable changed ,then the b******d ran out of ink , town and back .result +half day to print 3 pages...well P off

Much appreciated! Im having one of those days too, dealing with lettings agencies. How they can get out of bed in the morning I have no idea. I have 3 people all asking for the same thing, all working for the same company.

Im about to go down there and beat them with a phone.

I've always thought the baseball bat of further education works quite well...

that's a pretty good price for one of those! Saying that, I think Terry has one already, so will do that before shipping the engine off.

How is the car now?

Update (at last)

Unfortunately, I am none the wiser.

It also appears somebody has been into this engine before, the head gaskets have evidence of silicone sealant visible from the outside, as does the rear main seal retainer. So much for full service history.

Firstly, in progress shot, took me ages to get to this point because I'm crap. :



Plenums off:



Rocker covers off:



First indication of where the fault is...

The dark side is very sludgy crusty. Its like a layer of deposits over everything.




Head off and I was expecting to find carnage:





Not great but not horrific







And the head itself:




Soooo, no massive hole in piston, no massive gouged liners, but still this:

Best bet is still an oil control ring I think.

New engine is going in soon, its from an SL 55 so sumps/oil pumps etc need to be swapped. Suspect I may run into an issue there, but best leave that to later.

Smoke all the time normally indicates rings, smoke only when you rev after idle is valves.

 

[Flyinspanner]

Hope you get it sorted soon.

The traces of silicone around edges of the head gasket is from the factory. As you have it out, pull off the large plate that the rear main oil seal is fitted into. Behind it you will find a "U bend" that allows the oil to drain from the back of the right hand cylinder head, back to the sump. My money is on a blockage there that is probably responsible for your problems.

All clear at the back there, have had the plate off. Also checked that both the breathers drained oil back down to the head before I started, both did

Trust me this silicone job is not a factory one. Its obvious once the head was pulled off.

Fair enough then

I'll be interested to see if it is a broken ring. I'd have expected more scoring of the bore if that was the case.

Once we got that rear plate off, it was obvious somebody had pulled it apart, and put it back together again.

I said that too, but the HUUGE amounts of oil sitting on top of the valves is a mystery.

Thanks, this one is a mystery.

 

[Craiglxviii]

I'm going with oil scraper ring.

I think you were far to hasty to get heads off... to me all along was NOTHING mechanical, but I know nothing about merc engines and even less on supercharged ones.

I's say right bank was running hotter, hence fractionally dirty valve gear. And probably like any digital speedo car someone somewhere removed miles electronically. You can take 100 k of a well locked after car these days and 9.5 out of 10 wouldn't be able to tell. I'd put new gaskets on put it together and look for supercharger or controls faults


a second hand engine in my mind is much less than 50 50 gamble...

by the way never leave liners to own divices overnight or it will likely need whole engine apart to change the seal at the bottom.

good luck !!!
