I really screwed up in not taking better care of the car but I refuse to part ways with it because it has a lot of custom repair work with expensive parts. The car has had a valve job before. A blown head gasket caused oil to leak and corrupt the cooling system. I need a new radiator too. My mechanic says its going to cost $2500 to repair. He's offered me $200 for the car because I can't afford the repair cost.

Anyone have any idea as to how labor intensive it would be to repair the gasket and salvage/clean the egr valve and everything...

First, we need to know what kind of car is it.

I know Mercedes has a cleaner for the cooling system that has been compromised with oil.
The part number is A000 989 1025. It comes in a .5kg package and the retail price is in the mid $30 range. I am not sure how much you need to do a complete job of cleaning.
If you have been told that you need a new radiator because of oil suggest the use of this product.
What does the $2500 include? Since you had a valve job and IF the head itself is not warped then it's high. If you need your head rebuilt ($700 including machine work) and the various new parts then it's inline.
$200.....??? unless it's a rusty piece of junk the various parts alone are worth more than $200. But since he knows your financial situation.... once again mans treatment of his fellow man rears its ugly head.
Since you cannot afford the repair cost why not do it yourself? What have you got to lose? Worse case... you have a leaning experiance, best case... for around $500 in parts you get your car back on the road.
There are many placs to cut costs (and an equal number of places where not to cut costs), people on this board and others will help you along.
Just my .02 cents.

Re: Blown Head Gasket allowed oil to ruin Cooling System

How long ago was the valve job and was the head gasket bought from a dealer? If it was less than a year ago and the parts came from a dealer, MB should cover some or all of the repair under warranty.

Good luck,
Richard

Re: Blown Head Gasket allowed oil to ruin Cooling System

the cleaner ron was talking about is $20 list as of the new year. i'm pretty positive that you can clean out the entire system on your own and replace the gasket on your own. it's not a big deal. i'm sure someone on this list who lives near you would be willing to help out.

Re: Blown Head Gasket allowed oil to ruin Cooling System

Thanks everyone! Its an 88' 300E It had a valve job and used cam installed in 2004...I have a lot of the repair tickets. What are the advantages of using Bosch spark plugs as compared to using NGK plugs?

I've gotten mixed responses from everyone. These forums have definitely helped me out a lot. One person saying its going to be easy to do and another saying that I need special tools to make sure the tuning is correct. I understand the tuning part is crucial. But there has to be a way of being able to get my hands on some used MB tools?...Anyone have any suggestings.

Gotta be a company on the internet somewhere that I can purchase used MB stamp tools...

I'll get my mechanic to write up the estimate and post what I find. It included a couple other things like a faulty turn signal flasher and universal joint thing. But, I don't know what he was including.

Re: Blown Head Gasket allowed oil to ruin Cooling System

As to the tools and the service manual, my advice is to start by checking with some MB dealers who sell via the web or frequent this forum, and get an idea of the ball-park cost. Usually the service manual will call for special tools but you can get buy without (more labor time) or use an after-market tool. Samstag Sales has a wide selection of MB tools to compare vs. the dealer prices. Check Ebay and Craigslist to see what is available used, but don't expect to find too much. Study the procedure in the service manual, ask direct questions here about what tools are needed and if the official MB tool is the best choice. Weigh the cost of the tools and your time to do the work vs. paying your mechanic to do it, and make a decision.

Even though my time working on my cars is very limited, I know that I can do a quality job every time and have confidence that it was done correctly, so I do as much work as I can myself.

Re: Blown Head Gasket allowed oil to ruin Cooling System

Ok so Im going to replace the head gasket, head bolts, and seal on the ignition as well as cap and rotor. The radiator should still be good along with the water pump since they're both fairly new. Im going to take the radiator to a radiator specialist and have it thoroughly cleaned.

Anyone know of anything else I can do to service the engine while its torn down?

Re: Blown Head Gasket allowed oil to ruin Cooling System

Get yourself a nice set of long hex bits up to 24mm I believe. You can also buy hex bars. These are used for the timing chain tensioner and other items. You don't need to remove the tensioner just loosen enough to remove the sprocket and then retorque when you reassemble. (unless there is play)

You will need a 12 pt special tool for the head bolts, I cannot remember the size. It is a good idea to also replace the clutch fan, temperature sensors, thermostat, and all coolant hoses, including the little one attached to the head. Allow plenty of time to properly clean the threads for the head bolts and the block. Do yourself a favor and completely disconnect the manifold under the car and pull the head with manifolds attached. Be careful of the timing chain don't let it drop down if you can help it, I used zip ties in three places on the cam sprocket and a bungee to hold the chain on the sprocket. You can move the intake out of the way with a strap toward the drivers side and up, this will give you enough room to lift the head up.

And most important remember to hook up the overflow hoses correctly, as I have learned the hard way.

Good Luck

Re: Blown Head Gasket allowed oil to ruin Cooling System

My Indie MB mechanic said that I should take the radiator off and take it to a radiator shop. Perform a flush and do a tune up. The car is very healthy mechanically.

My main priority is getting the gasket changed sealing it and then focusing on the cooling system. I live at the beach oceanside and the combination of sand with the salty wind makes for a corrosive environment.

Im going tool shopping this weekend I can't wait!
