Even used engines aren't cheap

There are so many engine failures that even a used engine will cost $1200 to $1600. I looked everywhere and Advance Auto had the best price. They give a year unlimited mileage warranty on the engine itself. The labor is on you.

Tomb Raider 67k blows! Sorry for the loss! Never had issues with changing to synthetic in all my vehicles, old and older. Having worked in a race engine shop...sometimes things just happen, and specific causes go un found!

PTaylor you can get another engine pretty cheap, just the basic engine, and transfer everything from it to the new engine.


or sell it to me as is....

jefferyfghezzi Sounds like you spun a rod bearing and broke the rod. With only 67,000 miles on the JEEP I would probably look for remanufactured short block. Your crankshaft more than likely is scored. A salvage yard engine is good too,but I wouldn't want more than about 70,000 miles or so on it. Not knowing how it has been maintained I would be tempted to rebuild it just for the peace of mind. If you opt for remanufactured I wouldn"t want 10 or 20 under on the main or rod journals. I have gone 30 over and had no problems on the mains ,but I did have problms on the rod jounals.Thats just me.

mcware I wasn't driving, so i will tell you what my wife told me. Driving down the interstate, engine light came on, and then a loud band. No sign of overheating before the failure. Started pulling parts off yesterday, and found a hole in the side of the block. Haven't removed the pan yet, but sounds like a rod came loose. No oil in the radiator or coolant. I changed my oil myself using 10w30 pennsoil, before switching to synthetic.

jefferyfghezzi LIKE JDsDREAM asked WHAT DID IT DO?

ratuna Who has been doing your oil changes? You or a Goofy Lube type place?
02-08-2011 06:24 PM
JDsDream My first thought was the head gasket. Is there oil in the coolant or vice-versa? Did it overheat before it failed? Were there no signs that it was about to go?

KCrisp I've switched to synthetic in many older engines and never had a problem. If you have been using modern oil and changing it as recommended you just don't have a big build up of gunk to become loosened/dissolved. What "failed" in the engine, exactly? No cracks in block or head or leaky head gasket contaminating the oil with coolant?

InfernoGirl Pretty sure switching to synthetic is a bad idea on an older vehicle. I think it loosens all the build up and probably is what created the crud. I'm sure others with more knowledge than I will chime in soon. Sorry about your bad luck.

2002 jeep wrangler engine failure

I own a 2002 jeep wrangler that had an engine failure. it has 67000 mile on it. at the last oil change, i switched to castrol synthetic oil. after about 1000 mile the engine failed. the oil turned to a gum like substance. i have owned the jeep since new, always serviced it faithfully and it has never been in the mud. it is a 4.0 litre. any suggestion.
