try changing the oil a couple of times and see if the sludge works its way out before tearing the car apart. Does the engine still run? how many miles on it?

Change the oil immediately, run it for a tank of fuel, change the oil again, run it for 2000km or so, change the oil again, run for 5000km then change the oil with some sludge remover and hope for the best!

That's assuming it's as bad as you say :S

Andyman- yes it still runs pretty good and theres over 135,000 miles on it

I'll try the oil changes thing I use amzoil and do oil changes regularly but I'll try the flushes first, my mechanic told me that if a chunk of it breaks off and goes through the "something" it will blow my engine, what do you say?

My parents bought a 1992 e34 525 in 1995 with 40K. The PO didnt do any oil changes or maint, and put dino oil inside it. Needless to say there was a considerable amount of sludge inside the engine. They decided to clean the engine by taking it apart and removing oll the sludge build up. A 3K job, but the car ran fine until they sold it and bought my e39 in 99'. If your going to keep the car for a little while (1-3 years) get a used engine. If your going to keep the car for a longer period of time ( 4-8 years) rebuilt the engine entirely and see to it that you will be maintenance free (engine wise) for the duration of your ownership. Getting a new engine isnt a financial wise option for an older car. You couls sell the car in the near future and upgrade to something less maintenance intensive

There is another thing to try. Drain the oil and replace the drain plug. Overfill the engine with degreaser, maybe 2 to 3 gallons or more. You may have to plug the dipstick hole if it starts to leak, pour as much in as you can till you can see degreaser pooling near the oil fill hole. DO NOT START THE ENGINE!!
Let the car sit a day on level ground and drain the engine thoroughly. Refill with cheap grade oil and new filter, run engine till warm and drain oil. Refill with new filter and correct grade synthetic oil. Change oil again in 2000 miles using Lubrimoly oil flush before oil change and Bob's your uncle.

rebuilding, or actually cleaning it like someone suggested should be fun, if you have the tools, space and time.

im sure wurth makes some stuff for that. they seem to make every type of chemical and solvent related to automotives under the sun. And most all their stuff works too.
Liqui-moly is also an excellent brand too.

How do I get sucked into this sh!t.

If it were me, & I had a monumental amount of sludge under the valve cover, I'd do this:

First I'd pull the valve cover off & remove the oil drain bolt/plug, of course drain all the oil out. DO NOT reinstall the oil drain plug, leave it out.
I would then use a pressure washer feeding off of hot water & go to town spraying your cylinder head down. When you're done it'll be Very clean, all the extra water will go into your oil pan & 98% will drain out. Next, take an air hose & blow the cylinder head clean & dry, when finished reinstall the drain plug & valve cover. Now go ahead & fill it back up with cheap oil & a new filter, virtually any kind will do. Start it back up & let it idle until it comes up to operating temp, DON'T rev it up, 2000 RPM or less. Dump that oil & filter & add new cheap oil & filter; this time drive it for a day or two gently. Dump the oil & filter one more time, this time refill with high quality Mobil 1 & a premium filter. You're all done.

This will work just fine, I've personally seen this done before.


Good luck.
