Default some fluid leaking probs w/pics

so, i had some cams put in a few months ago. since then, id smell oil burning when i was stopped at lights and the such. reall faint. i checked my oil quite often, but didnt took a long time for it to show it being low. and that was also while being on a 3 week road trip of about 8 hours driving days. i had the oil changed after about 2 weeks. and right after that it leaked more even oil. before that, it only leaked while i was driving. after the oil change, it leaked even while it was parked. a month later, its back to just leaking while i drive. now its also leaking antifreeze. more often, and more than the oil. i took a look underneath... it apears that its all comeing from somewhere under the timing belt cover, where it meets the block. the oil drips right onto the header, and thats why i smell the oil when i stop. mostly the same for the antifreeze. the guys who did the cams, also put in new gaskets for anything they took apart. one of those guys is a suby mech at my local dealership.

i had the cams, valve springs, valve retainers, new clutch, flywheel and new timing belt all installed at the same time. do you think the leaking is from something they did when installing all that? is take it back to them to look at, but that was all when i lived in NY, now i live in new mexico.

here are some pics of where its leaking from... also, i looked all over, and i couldnt see anywhere else on the block that is wet. not near the heads or valve covers, a little at the front of the oil pan and block, but that i think is from where its coming from, from under the timing belt cover. also, i kinda dont think it wol dbe leaking antifreeze from the oilpan gasket.




any feedback is really appreciated!

You are going to have to pull the front covers off and clean it up good and then find the leaks. The antifreeze is scary- might be head gasket issues. Is it a high mileage motor?

Question

Got any paperwork on the repairs? Check to see if new headbolts were used. Theres been numeruos TSBs from almost all manufacturers in recent yrs advising new headbolts on any aluminum headed motors. I dont mean to throw rocks here but someone has obviuosly done something wrong or it wouldnt be leaking. You might get dumb lucky and retorque the heads but I would reccomend another teardown if its head gasket.

Default Crank Seal and Water Pump

Crank seal or loose bolts in the back of the oil pump for the oil. As for the anti-freeze, start simple and check your hoses. However, it looks like the water pump could also be starting to let go.

Do you have the front bolt out yet? Stick a screwdriver in a slot on the flywheel through the timing port to hold the motor from turning and loosen the bolt on the front of the crank and it will almost fall off in your hand.

cant tell where the oil is comeing from so far. tomorrow ill look around real good in the sunlight, and with a mirror. ill take some high res pics of that tomorrow too.

First thing first, once you get the covers off, put the crank bolt back without the pulley on the align the timing marks. Turn it clockwise.

You will need to remove the crank timing sprocket to inspect the front main seal. If it's bad then you'll probably have an oily belt=replace. If it's clean then it's probably the oil pump grommet.

The t-stat elbows are plastic an the rs's. I wonder if the bolts need to be a little tighter. MAybe the gasket has mushroomed out a bit or cracked. The t-stat might be in there a little cockeyed.

Don't forget to drain the coolant.

Oh and btw, so far I have'nt seen anything that would suggest that the person who worked on it did anything wrong. So far. removing the heads and doing the timing belt does not require removing either the oil pump or the water pump. The oil pumps leak. Subaru has redesigned the grommet already so they know it too.

Looks like a normal subaru with 100k miles.

Sure looks like my car a while back.......



You'll want to get to this and replace the front oil seal (assuming your camshaft seals are fine)

Here is seal part number:

Man now thats an OIL LEAK! I replaced the pump in mine about 5 yrs ago for the previous owner and it wasnt that bad, Ive also heard about the rear plate coming loose on the pump- might be worth looking into.

My head gaskets are leaking oil, but I'm replacing them this weekend along with the cam seals, crank seal, valve cover gaskets/etc...

It'll be fun.

hmmm, i think the belt is oil free, but ill take a closer look. where would i see the oilpump grommet?

sorry for all the questions on simple things.... i am mechanically inclined, but this area on the engine is uncharted terratory for me, and i dont know much of these parts by name... yet.

Looks like you need another new crank seal.

Proceed with the inspection though. I'd like to see behind the crank sprocket.

Nice pics btw. IT makes it so much easier to diagnose.

How does the area around your oil sender look?

here are some pics of the crank seal.










and these are taken from under the crank.










it looks to me like its leaking from between the crank and the seal, not the seal and block.

im going to try to get a new seal tomorrow and change it. and also try to find the coolant leak. maybe get it all buttond up tomorrow. maybe, hehe
