Saab timing chain tensioner seals that leak and assumed to be timing cover or head gasket leaks

[@haon4562]

Like he says don't insert the whole assembly back in , in extended position. Install the large part first in retracted position. Have to be extremely careful not to cross thread it. Very fine thread and soft Aluminum block. Use fingers and be very patient, socket will cross thread it (27mm). Then carefully install the plastic piece and the spring. Screw in the capping nut and it will adjust to correct tension.

I did this on my corolla 1998 and my son's corolla 2002. From time to time, oil leaks returns. Tired fixing them. Hope those who did tuis made it a success.

Is a 2003 Saab 9-3 2.0t timing chain tensioner similar to this one?

[@Bmw533ia]

Thanks dude. That was helpful :)

[@charleshuggins5814]

just got a saab and i was told the tensioner is bad because its having chain slap. Anyway when installing the new one, do i just put in and then pull the pin? Thanks in advance

Charles Huggins Yes put in then pull the pin easy. If its really chain slap you will probably need something else these almost never cause that problem

Hey guys if leaking (seeping) bottom through the timing cover gasket can the tenisioner be the cause ? or gasket failure is this common , re torque the bolts around there ? what is common sign of tensioner failure ? cheers

[@atomicautoservice50]

No then the leak is the head gasket and or timing cover. Most of them we have had good luck cleaning off really well and getting JB Weld and covering that area so it does not leak. Make sure you check your crankcase pressure as well

[@223x8]

Atomic Auto Service Thanks when you talk about JBWELD what part are you reffering? Timing cover gasket leak is common problem also minus other issues? Any easy way to test crankcase .?

[@atomicautoservice50]

We test crankcase pressure with an oil school fuel pressure gauge for a carb. Im talking about JB welding the head gasket/timing cover joint where it leaks

this is great. i think im leaking from this park...losing aboutt a quart every 500 to 600 miles. the entire passenger side of the engine is moist from oil. Crank case seal is not bad because i would have a puddle of oil on my driveway, and i dont see that.. whats your thoughts everyone? BTW 185K miles on an 02 9-5

[@travisdecker7153]

fix this first clean off oil see whats leaking. Check your crankcase pressure as well

[@KylePancis]

The check valve went. Iv been thru the works since fixing leaks. Did valve cover. Oil pan. Oil pressure sender.
