replaced timing belt, now big oil leak
I have a 2002 Honda Accord, four cylinder.
I hit the 100k mark for mileage already because of my long commute and had my mechanic change the timing belt. He also replaced the water pump as Honda recommends and flushed the radiator. Two days later, I notice quite a bit of oil in my garage floor. I check my oil and I've lost about two-thirds of it. Darn oil light never came on. Do you think the timing belt replacement and the new oil leak are related? I've never had a problem before. |

Two possibilities:
The valve cover (a.k.a. "cylinder head cover") has to come off to do this job. If it's not replaced carefully, its gasket won't seat right, and oil will be spewed all over the exterior of the lower engine. So inspect the lower part of the engine. Try to see where the film of oil stops. If it stops near where the valve cover seats against the cylinder head, I'd take it back, explain your suspicion and the problem and ask if they'd be willing to put a new gasket on, in the name of good relations. If they won't, I'd eat the charge, because the gasket should be changed every 100k miles or so anyway. Here's a drawing of the gasket and valve cover: http://www.hondaautomotiveparts.com/...mws/prddisplay. jsp?inputstate=5&catcgry1=Accord&catcgry2=2002&cat cgry3=2DR+ LX&catcgry4=KA4AT&catcgry5=CYLINDER+HEAD+COVER It's also not a hard Do-It-Yourself job. Another alternative is that they damaged the oil pan. On many (all?) Hondas, at least one engine mount has to be freed for the timing belt job. The mechanic has to support the engine in an alternative way while completing the job. For my 91 Civic, one puts plywood and a jack underneat the oil pan. If done incorrectly, the oil pan will become damaged. (One shop did dent my oil pan!) Look for leaks in the vicinity of the oil pan drain plug and around the oil pan's gasket. You'll have to get under the car to see these. Maybe refill the car with oil, drive it a few miles, then put a big piece of cardboard underneath, and trace the drips to the source. Re the oil pressure light not coming on: Some kid at a private shop was troubleshooting a no start condition I was having while on vacation and took off the valve cover for an inspection. I watched him do it, and know he sped through putting everything back together and was not attentive to the valve cover gasket. About a thousand miles later, I found the oil level on the dipstick barely visible. Naturally I found the exterior of the engine covered with oil. But my low oil pressure light never came on. The car is fine, 40+k miles and a few years later. I replaced the valve cover gasket, following the manual's directions and those of people here carefully, and all was well.

You will have full pressure up until the second the oil level becomes one drop too low, at which time the pressure becomes zero, the light goes on - and the engines becomes toast - all in the space of a second or two. |

Did they change seals when they changed the timingbelt? They usually
do. Perhaps they did not get one on right, or forgot it completely.

If the oil light EVER comes on while you are driving... your engine has
been starved for oil and some damage will be done! As for the leak... if I remember right the oil dipstick tube needs to be removed for this job. It may have not been put back in correctly and oil is leaking out the tube. Look carefully. -SP JLA wrote: > I have a 2002 Honda Accord, four cylinder. > > I hit the 100k mark for mileage already because of my long commute and > had my mechanic change the timing belt.
