I bought this SC300 over a year ago with 110,XXX miles now and replaced the valve cover gaskets a few months ago so there are no leaks but,now it's leaking not from the valve cover but,what we think may be coming from the cam seal maybe?And an oil leak coming from the rear under valve cover?Also we found that the harmonic balancer was replaced but,is this power steering hose suppose to go there so close to the belt?Any help or advice where leaks might be coming from.

Leak in front looking in from the distributor


Leak in the rear


Is this right/wrong??underneath view

Kinda hard to differentiate what's what.. try and back up and take some pics, and if you can, circle where it's leaking.

But if you're leaking by the distributor, it may be the distibutor o-ring.

Don't know where in the rear.. unless your valve cover is leaking again.

If you're leaking from the crank pulley, it could be your front main seal.

That picture reminds me of mine before the cam seals were replaced. Had a drip in the exact same spot onto the alternator. New cam seals and good as new. Good Luck.

distributor o-ring is leaking in Number 1

Number 2the rear half-moons under the valve cover are leaking, need FIPG or equivilant for that

Number 3 could be cam seals or the front main seal. Either way, both are good signs that you need to get a new timing belt. Also get a PCV valve, yours may be clogged and causing all this, only a few bucks at any auto parts store and easy to replace. It will help prevent leaks like this from happening later on.

Well it's leaking by there but,when we took the cam gear cover off we can see it leaking behind the pulleys also.Just don't know what seals to order before all this is taken apart.

You should go ahead and replace the timing belt, cam seals, timing belt tensioner and front main seal because the crank pulley will be off when doing the timing belt. Hope this helps.

Yeah,was it leaking toward the front too?How many miles were on it when you replaced it?
