does anyone on here know how to remove the rear backing plate timing belt cover? l have an oil leaking there and l want to remove that and take a close look at where the leak is coming from.thanks

Rear Backing Plate Timing Belt Cover - P80 850 S70 V70 -1998

 

Grrrrrrrrrr. Cam seals, crank seal, or cam cover. You have to take all the timing cover stuff off then 2 screws I believe.

 

where is the crank seal located? there is noo leak visible from the cam seals.it is right on the cam cover.is there a seal for that cover?or could it be broken allowing oil to leak?

 

No, there is no way that cover leaks. The crank seal is very low, where you turn the motor when doing the timing belt. That is the crank.

Clean it up, it's really hard to see cam seal leaks because they only leak when the car is running and the wind pushes the oil everywhere.

 

l happen to break just a tinny bit of the head when l was changing my lifters.you know where the cam seals sits on the head?l broke a lil bit piece of it when l was taking the camshaft out.it was hard to take it out.could that be the cause of the leak?

 

Best bet if you can't locate the leak is to add some dye to the oil and use a black light to follow the trail back to the offending area.

Do you have any pictures of the damaged head area?

First picture is not engine oil dye but it's similar. Just add it to your oil, available at auto parts stores. A black light helps it fluoresce. Black light bulbs are available at places like home depot.

 

While reading around the past month, I have read where a few people did do the same thing. Removed the cam put not straight up and it chips the head or cover. Usually the cam seal is out far enough to keep the oil on the inside of the motor.

Not sure what to say without seeing it. If it's the cam seals you should see a little oil there. Depending on how large the chip is, you may be able to pull the seal out a little to keep it from leaking. Wipe the seal area dry and drive it a few minutes and make sure it's still dry. Other than that, how well of a job did you do with your anerobic sealant when you put the cam cover back on? Do you think there was a chance that you got oil on the head and caused contamination when you put the top back on?

 

there is not a bit of oil on the upperside of the head where the seals are located.it is underneath the water pump.l dont know if the broken seal caused that.here is a pic of it.

you can see the lil space where the cam seals sits? thats where l had a crack.it did not break all the way just a line of crack.l filled up the crack with a sealant.l was just wondering if that could cause the oil leak.

 

sorry but l dont have pictures of it. the oil leak is right behind the water pump. will the oil dye seal any damaged area that caused the oil leak?

 

Both cams sit in a machined guide by the timing gears behind the seals. If you lift the cams from the rear without getting the cams out of these guides you will break a section of the guide out. .....is this what you broke? If it is, it will not cause a leak and/or a problem with the performance of the cam. Pretty much, no harm done.

 

yea that is what l cracked. thanks. it is really hard seeing where the leak is coming from.and l am loosing oil real bad.l had my oil at the full mark and today l checked it is in the middle.l dont think l am burning oil because l dont see any blue smoke coming out from the tail. l think the leak is making me loose that much oil.strange.l am dropping my oil pan monday,l will take a very close look at it.
