Unknown Oil leak
 

Hello guys.

First time posting something here. I bought my frs, last yr August. Completely stock with about 18,500 miles. I was doing my first oil change around 22,000-23,000 miles at my work, noticed it was leaking oil. Leak looked like it was coming from the timing cover. Called my local Toyota dealership, set up an appointment. They confirmed it, oil leaking coming from the timing cover. Timing cover re-sealed under warranty. I was pretty happy until 6-8 weeks later, I checked it again. It was leaking again, from the same spot. Went back too Toyota. This time they said, leak coming from the dipstick o-ring. I thought it was B.S. but I went along with it and I didn't say anything. I checked again, 3 days ago and omg lol its leaking pretty bad. I called them immediately, set up an appointment. I drop it off this morning, a few hrs later they called me. Saying, they have no idea where's the leaking coming from. That they going add dye, too spot where the oil leaking is coming from. Now I have too wait a couple days. My only guess a crack timing cover. I took 2 pics. Any of you guys had a similar problem? Much help appreciated. I will keep updating, when they call me from toyota.

Hello @adrianfrs and WELCOME to ...... The Forum .......:clap:

Yep, it appears you car has a oil leak for sure.

Yours hasn't been the first one to leak around the timing chain cover.

You may wish to review several of the old threads to get some background.

As long as it's under warranty, I suggest you let the dealer sort it out ..... and try to relax and be patient.

Thanks humdrz!

The thing is, they already re-sealed the timing cover and it's still leaking. Now, they're saying they have no idea where's the leaking coming from. I'll keep looking on here. And, yes. I'm definitely been relax and patient with the advisor. No need to be aggressive haha

My suspicion is that "they" do more damage to the block and timing chain cover by removing it, than they do good by trying to reseal it.

It appears that the two parts are made of aluminum and glued together pretty darn tight. So, either of the pieces could easily be damaged by "prying" them apart.

Maybe the manufacturer has a "special tool" they use ....... but I doubt it. They probably use a small crowbar and/or a fat screwdriver, which could easily leave a section of the aluminum stressed or grooved.

Since this leak is relatively small and not likely to get larger and not dripping on anything significant ....... I would be tempted to just leave it be......:sigh:

Obviously, I do not have an OCD problem.

Back-in-the-day many of us drove cars with various oil leaks ....... and as long as it wasn't leaking on the clutch disk or the brake shoes or leaking more than a quart a month ....... we just drove on ....... ;)

Give this a read through
Maybe they are not aware" I am not even sure there is a Toyota version but this still apples for info purposes.

Back in the day I had cars that if they were not leaking I would have to try and figure out what was wrong. It usually ment that I had simply forgotten to fill it back up.

Interesting information.

The referenced manual would be interesting reading ........ especially on how they separate the timing chain cover from the block.

"2. If the front chain cover is leaking and needs to be resealed, follow the repair procedure in the applicable Service Manual."

Yep, fer sure ....... they will just leak so much ..... and then they won't leak no more ....... ;)

If a differential leaked ....... pump it full of grease; if the transmission leaked .... put thicker oil in it; if the engine burned oil ...... put heavier oil in it ....... simple ....... huh ...... :D


humfrz

Head gasket or rad little bit of fine sawdust would usually do the trick.

Hey, thanks, there Tcoat ...... :thumbsup:

So, it says to the split the cover off of the block using a wrapped flat tipped screwdriver ....... with a big CAUTION at the bottom of the page.

Now, with Bubba at the other end of the screwdriver, what could go wrong there ....... especially, if he didn't read the caution ....... :confused0068:

I would prefer to use a strong, thin putty knife, tapped in gently, following some gentle heat from a propane torch.

Oh, well ........ OR just bring me a big fxxxing hammer and a cold chisel and we will split this puppy apart in short order ...... :paddle:

Another edition of porch-side talks with @humfrz and @Tcoat

lmao :p

Oh, yes, or a cup of oatmeal in the radiator stopped a lot of leaks ...... :)


humfrz

Yep, all that's missing is sitting around a pot belly stove in the shop, smoking cigarettes and drinking whisky ....... :respekt:
