Man that sucks. Sorry to hear.

They're now claiming the oil is leaking from between the oil pump and the block causing the oil to be carried around the timing belt routing.
If this is true, how frequently does this happen on the 2uzfe?
Can changing the timing belt and camshaft seals possibly cause this?
How involved is this to fix?
Thanks

Never heard of a factory, untampered 2UZ oil pump leaking or needing replaced. Sounds like horse**** to me. Did they provide photos? That would be tough to prove.

They said they put dye in previously to try to determine where the leak was coming from.
I would inspect myself or get a second opinion at this point. That shop has proven to be a bunch of bozos. How much are they wanting for it? Are they charging for ‘troubleshooting’ if you simply say no thanks?

The current leak is a hell of a lot more than what was leaking when I first had the camshaft seals replaced.....because of a leak.

No additional charges since the initial camshaft seal replacement.

I have never seen a oil pump leak on a 2UZ. It’s not a small repair. Pretty sure the oil pan has to come off to do it right. Looks to me like you have multiple leaks. Most likely caused by poor workmanship and/or misdiagnosis. Personally I’d take it somewhere else. Have them clean it and see what is really leaking.
A cam seal or the front can bearing cap leaking will make a mess. Will drip all the way down front of motor. That might be all it is.

F that. Depending on how bad its currently leaking Ill add some oil stop leak additive and if that doesnt work, just live with it and call it a day.
Any way them doing any of the timing belt, water pump, camshaft seal replacement could have caused this?
I don’t think so. But like I said before I’d clean it up and make sure it’s actually leaking from oil pump and not running down from the cam seal or front cam bearing cap. They had to remove the cam bearing caps to do the cam seals. Probably didn’t reseal them right or damaged the seal during the repair.

They said they applied a dye to try and figure out where it was coming from. Still possible even with the dye to misdiagnose its source?
I asking around for estimates from another shop to diagnose an oil leak source and they quoted around 330ish to remove all the covers, harmonic balancer n such to look at that area to see. 3 hrs of work. Does this seem accurate?
Any recommendations on oil stop leak? Blue devil was on my list.
3 hours for the diagnosis seems right. It’s a lot to remove to get down to the timing belt then put back together, then diag on top of that.
I’d approach the second shop without too much backstory. Just ask them to find the leak and see what they say.

ok cool. Ill add the stop leak....see if that works well enough and if not, take it to the shop.
I wouldn’t add stop leak. I’d first determine if the original shop owes you a new cam seal.
This is all a headache man, I get it. I have been there plenty of times on past vehicles and ultimately end up spend hours and hours and hours in my garage doing things myself and $$$ on getting the right tools for every job. It ends up seeming like less effort than having a shop mess things up multiple times in a row. Time spent dropping the vehicle off, over and over, mental energy, money spent on shoddy labor and part marktup... What's shocking to me is how many shops, even supposedly good ones, get away with poor work or using crap parts and most people don't know the difference. At least you got them to fess up the first time. Once it's done right you'll have a solid rig for a long time.

I hear ya 100%. Normally I do most of my general maintenance precisely for this reason. I stop short with things like the timing belt on interference engines or massive time syncs. Ive definitely had my fair share of dirtbag mechanics jerking their clients around.
That being said Im a little hesitant to drop the vehicle off yet again to another mechanic to troubleshoot. Even if they find the cam seals are leaking.....the first shop will take their word for it? And im out another 300+ (half the cost to replace the cams seals to begin with) Im just sick of the whole thing.
