I need straight, realistic advice. The 2.6 engine in my 1993 190E Sportline is shot--at least two bearings burned.
I'm going to keep the car--even at 110,000 miles, it's near perfect in every other respect, and there's nothing else I like as much. Also, it has a new auto transmission with less than 20,000 miles on it.
There are four options for replacing the engine:
- Let the dealer do it with a new long block from Metric Motors--4 year, 50,000 mile warranty. Cost--at least ,000.00. (Dealer will do a short block, but says the cost will most likely be about the same, and only 1 year warranty.)
- Buy the long block and do it myself. Long block, with shipping, about 00.00. Plus whatever other parts I need--engine mounts, gaskets, etc. 4 year, 50,000 mile warranty on long block.
- Buy a short block and do it myself. Assuming head is OK, about 00.00 plus other parts and machine work on head, etc. (Warranty on short block is 1 year, unlimited mileage.)
- Buy used engine and do it myself. Cost--much cheaper, but many unknowns.
I have very good mechanical aptitude, and am systematic and painstaking in my work--but I haven't done any major automotive repairs since I rebuilt an air-cooled VW 25 years ago. (Did a good job, and VW engine was still running great five years later when sold. But obviously a huge difference between that and a Mercedes engine.)
I've got all the basic metric hand tools, but that's about it. I'll have to buy/rent everything else. I'll fortunately have the time to do the work essentially uninterrupted--I figure at least two weeks. Sound about right?
Should I even consider doing any the work myself? If so, which approach would make the most sense?
Thanks.
