Smile advice please.....

i know people are going to say...if you love your car....

question....i just priced having my rear main seal and oil pan gasket along with head gasket done.....car is 1980 300sd

would anyone else do the same work?

the cars a monster...a very straight car, even with a bad rear seal and head gasket....

question again is if you were looking at that much work, would you do it or go towards another diesel/gasser?

any thoughts are appreciated

I assume we are talking about $2-3000 of work, correct? It really depends on the overall condition of the car/engine and your long term plans. I've recently spent more than that on my engine with 300+K miles, knowing I would not recover the money if I sold the car, but I don't plan on selling. The cheapest alternative might be a replacement used engine, but I don't trust used engines.

You mean, you don't trust used engine suppliers, right? I don't trust very many suppliers who sell things with moving parts in them either...LOL

Well, if you love your car....lol, Just kidding.
I think Craig, made an excellent point. Just base your decision, on your long term plans for the car.

My Used Car Philosophy...

In case anyone cares (what does it matter I'm telling you anyway)..

If you have a car in hand that needs major repairs and is PAID FOR....

Are the cost of the repairs MORE than it would cost you to go out and purchase another comparable car of unknown pedigree?

If the answer is yes....then forget the repairs, part out the car or junk it and use that money to buy another one.

If the answer is no (or even very close) I say the devil you know is better than the devil you don't. ANY used car (full service records or not) you buy is going to cost additional $$ over the purchase price so you need to factor that into your equation. There are very few repairs that it doesn't make sense to go ahead and have done vs. getting rid of the car unless you just see a money pit ahead.

In my case - I already KNOW what I've done to my cars and would rather KNOW what I have than begin fixing what someone else forgot or neglected.

Hope you keep it.

John

i am with craig and the bunch. i just spent $2k for a tranny rebuild on a car that i paid $500, but i am not planning on selling it anytime soon. IMO the $62/month on the cash advance from the Credit Card is mych cheaper than the possibilty of getting a bad vehicle or a newer payment.

The bottom half of the rear main seal and the pan gasket can be replaced without pulling the engine. I'd give that a shot before pulling the engine and replacing the whole gasket. You've got a better than 50% chance that the seal is leaking in the bottom half and not the top.
Also a leak at the valve cover can sometimes appear as a rear main seal leak since the oil can run down the back of the engine and appear to be coming from the rear main.
The head gasket doesn't have a lot of options if it's blown. Whether I spent the money to fix it would depend on how many miles the engine had on it, it's maintenance history and my judgment about its future life with a new head gasket.

Exclamation See above posting by Kerry Edwards...

He makes a real good point.......about the Valve Cover gasket.......maybe you should pressure wash your engine, and locate the exact source of your oil leakage......and why do you think that you need to replace a Head gasket? Do you have water in your Lube Oil or Exhaust Gas in your Coolant??
