1995 3000GT Repair Questions

I have a 1995 Mitsibishi 3000gt base model). It has 130,581 miles on it. The engine is 3.0 DOHC 2WD. I have two questions. Oil from valve cover gasket leaked on the timing belt causing it to snap. Two valves were bent. The mechanic charged me a total of $2400 dollars to have the following parts replaced. This is off my reciept (crank sensor, water pump, spark plugs, timing belt tensioner, timing belt tensioner adjust, timing belt, v/c gasket set, head gasket set, timing belt idler, ignition wires) - $600 was for labor - 7 hours of work. My first question is was this a fair price? The day I got my car back, 3 hours after driving I got stuck again. The mechanic now says that the oil pump failed and my engine is shot. He said he would get back to me on pricing? Is the mechanic responsible for all costs of repairs? Shouldnt he have checked the oil pump when he did the initial work? Is the mechanic liable considering It broke 3 hours after I got the car from them? Please answer asap.

I own a small shop and I do repairs also and I and most people would not have checked the oil pump doing a timing belt and head replacement. However there is a chance that he drained the oil out due to contamination of oil from coolant/gasket he scraped falling into the engine. If this is the case then yes it would be his fault. Check your oil and see if it has oil init if so oil pump failure would not be his fault. I hope this helps and good luck!

Thanks for response. I dont have the car, its at the mechanics. He did an oil change when doing first repairs as well as replacing the water pump he did a coolant check. Does that count as liabilty? I would assume that if your doing an engine job you would check the oil pump. The reason why the belt snapped was due to an oil leak. Please respond with this additional info

I always replace the oil pump if I am working on the lower end of a engine. However the head and timing belt are on top of the engine/upper end. I don;t think there is very many Mechanics that would check the lower end if all that is getting replaced is head and timimg belt. I don't see any liabilty issue with him no checking the oil pump. If he changed the oil then He took every step he could to make sure that nothing he did could cause damage to your engine.

Even though an oil leak caused the belt to break? What about the cost of the repairs? Do you think 2400 was fair price for initial work? Also what do you think Im looking at here if he said the oil pump went and the engine is shot. The parts he already replaced have a warranty so part of the engine shoudl be covered. Any further info would be appreciated

I found on 3sx. Com site it says that If you are doing anything with the crank (rebuilding motor, installing new or reman crank, new bearings, etc.), It is recommended that you install a new oil pump. He had replaced the crank sensor along with timing belt and gaskets. I would say that makes him liable!

As far as the oil leak goes that was caused due to a worn valve cover gasket. The crank sensor is just a sensor not part for the crankshaft itself. I would replace the oil pump if I was working on the lower end of the engine/ CRANKSHAFT, ROD BEARINGS, MAINBEARINGS, AND ANY ENGINE OVERHAUL but no during a timing belt and head replacement. You have got to remove the oil pan and on some models remove the motor mount bolts jack the engine to get room to remove the pan to replace the oil pump. If the car was running and not making alot of noise then it failed after it was picked up from the shop. I think the price depending on parts is in the ball park for most shops. I must stress again the crankshaft sensor is just a sensor that screws into the block not a major repair. Also if the head was just installed and no upper end damage has been found you can reuse the head for a short block just buy new gaskets and headbolts. However I don't know the price of things there but I found a low miles 2.0 DOHC cheaper than I could rebuild one for may do some shopping around before you make a choice. I hope this helps.

Thanks for your quick reponses. It just seems really strange that less than 3 hours after I left mechanic I break down and it happens to be the oil pump that went. Something smells rotten! TBC
