Time for High Mileage oil for very slight timing cover seepage? #5323404 01/15/20 11:59 AM

Long story short, I thought I had some coolant seeping around the water pump. Local shop confirmed it's not coolant but a slight oil seepage above the water pump coming from the timing cover seal. Almost 70K miles on the engine. Is it pretty cut and dry to start using something with some seal swellers?

Seal swellers work on gaskets. Yours probably has a sealant bead in between.

Why not replace the part instead?

Haven't gotten that far in research. Have no idea on price/labor.

What kind of engine? It could be silicone but also could be a big o-ring. Is the timing cover plastic or metal?

2.0L Skyactiv G. If I had to guess I'd say plastic knowing modern cars but not certain.

If it's a rubber seal, a HiMi lube might help restore it's elasticity and size.. or not. Just depends on how badly it's worn/damaged, sometimes seals are just too far gone for a mechanic in a bottle. Run a HiMi for an oci and if it hasn't stopped leaking, you're gonna need to replace it.

Fwiw, +60k on a seal or gasket seems like a short lifespan. Is this normal for this engine? You might research it before buying an OE seal.. maybe there's higher quality seal/gasket our there?

#1 it's a very slow seep, like maybe a drop or two per OCI. #2, If it's timing cover seal, it's rather expensive and labor intensive. not like a valve cover gasket which is easy DIY and $10. #3 I agree on 70K and having leaking seals already is BS.

Anyone here ever try Liqui Moly Motor Oil Saver for oil leaks vs hm oils?

Timing Covers on modern engines are sealed using RTV. Seal swellers have no effect on RTV.

My 2018 Ford Taurus had a timing cover leak at only 3,000 miles. I waited to fix it at about 8000 miles. On that duratec 3.5 L the whole timing cover was sealed by silicone. A himi oil would not have any effect on that. luckily for me it's under warranty, and for your info the duratec 3.5 L was developed by Mazda.

That timing cover is all sealant. See:

2.0 timing chain repair

About 2/3 of the way down you'll see the instructions for re-sealing and installing the timing cover.

Almost all of those motors I see have a little seep from that area, all the way back to the MZR 2.0/2.3 days. I wouldn't worry about it much, just degrease the area to clean it up and watch how long it takes to re-form.

I'll tell you this: re-sealing a timing cover in-chassis is NOT fun, in any FWD car. You have to be exactly exact, or it will leak.

Timing Covers on modern engines are sealed using RTV. Seal swellers have no effect on RTV.

Depends on what's in the seal conditioner. Some silicones are susceptible to swelling (increased volume) when exposed to certain chemicals. It just depends on the chemistry of the RTV. See the following link and pic...

Thanks guys. I will likely just clean it up once in a while and not worry about it unless it gets much worse.
