Rear main seal (slow) leak on a acura 95 legend. how soon should it be fixed and how much will it cost?

I bought a 2000 RL used, with some factory warranty remaining, and then bought an extended warranty. While hnder warranty, car began to smell up my garage from fumes from oil dripping onto hot exhaust. Not enough oil at that point to show up on garage floor. Complained to dealer about the odor but Acura Master Mechanic (said he) couldn't find source of odor (although I told him I suspected an oil leak because I had prior experience with oil leaks and resultant smells on another car). On the next service visit after the extended warranty expired, same master mechanic said my RL's rear main oil seal was leaking onto exhaust causing odor. And the dealer wanted north of $1000 to fix it. I declined. Leak has steadily gotten worse - now visible drops on garage floor. An independent repair shop quoted $650 plus the cost of replacing expensive, special Honda transmission fluid. Took my complaint all the way up the chain to the head of Honda in Japan, but got no assistance. No more Honda products for me.

That old of a vehicle it could be leaking oil from a lot of different places,

You need to have someone you trust to look under your car for leaks. For that amount of oil loss the leak should show a trail of oil.

There is a rear main seal and it is where the transmission and engine join. Often the oil pan is in the vicinity of this part. Perhaps the repair was misdiagnosed and you actually had a bad rear seal leak instead. Depending on how this style seal is removed, it may require separating the engine from the transmission. Or the repair did not last and you should go back to have it corrected.

If there is no leak under your car, then the oil is going somewhere. The valve seals are the next most probable place.

I hope my solution is helpful, please rate my info.

which seal? front crankshaft seal,rear crankshaft seal,oil pan seal, there are several more.

Main relay costs about $80. It is buried deep under the dash, hard to access and usually labor is about 1 hour to replace at a shop.

$570.00

sounds like the torque converter seal is leaking. trans will have to be pulled in ordr to fix, or just keep a real sharp eye on the fluid level.

a 91-95 bodykit will not work unfortunatey.but you can purchase one for older legends. Try Hondatuner magazines website

Sounds like bad valve stem seals. Idle is a high vacuum condition in the intake system. That will draw oil past the seals when they are worn. At worst, the valve guides are also worn. Good luck.

your water pump is leaking and most likely you had a small oil leak under there also and now the coolant is washing it out, don't go too long with these leaks because your timing belt is under there and is getting soaked with oil and and coolant this will break or slip off causing major engine damage to result (i.e bent valves) good luck and please rate -jeff
