Thread: LIM leaking. can i just add oil for now?

where are you located? A lim on a 3800 is only a 3-4 hour job iirc according to the dealerships.

Thought it was a six hour job. Regardless, still a chunk of change.

As for the coolant, you should have 50% water, 50% coolant. It doesn't matter what's in the overflow tank - it matters what's in the radiator.
Change the oil, get a nice filter, change every 3-5,000 miles and put in copper spark plugs (for cheapness) and change them every 10-15,000 miles since burning coolant will eventually ruin spark plugs. Keep an eye on things. Unless the gasket is catastrophically borked, the vehicle will operate. When it's catastrophically borked, the engine may hydrolock. So... when things get bad and oil gets milkshake-y, that's the razor's edge you'll be driving on. Try not to let it get that bad. I'm by no means an expert, but unless you're seeing major issues yet, I'd say you might have 30,000 miles on the clock before d-day. Just... do the gasket job before then.

I'm thinking its a 6 hour job on the 31/3400 and a 2-3 hour job on the 3800 though i'm not sure. It's been a while since i looked it up.

Nope.

Meh. Personal choice.

contact Oh4compg, he's in a GP local club out there and if he doesn't do side work, he'll know someone that does. There's no need for that repair to be $1,000

I'd they can confirm that it's the lim gasket that would make it easier to advise you. I've seen head gaskets leak oil into the coolant but these cars don't really blow head gaskets often.

I only paid $400 total for a local 3800 guy to do it. RockAuto for gaskets wayyy cheaper than Napa or Advanced ect. The local guy made some change I saved some win win. Sounds like OH4 is willing to dish out some assistance and already has good reference.

looks like multiple oil leaks, they put a UV dye in to check in a week. so not sure where they're coming from now

pick up a used radiator and swap it. the oil leaks, take a paper towel, fold it up, and when the engines cold, wipe the under side lip of the rear valve cover, it could be all wet and running down the block and making a mess. not that a oil pan has never leaked either.

Not a good idea at all... will clog more than just the leak!

ok apparently i have 4 oil leaks. i attached the estimate. maybe you guys can give me some insight?

Your lower intake gasket can be done yourself for $100 and your front crank seal and oil pan gasket probably aren't to bad but it's hard to tell without seeing it. Change your lim gasket and see how much better it is.

If that's Midas..they are guessing. Personally, if you want to know where it's leaking. Clean it. Then drive a little and see where it's actually leaking and where the leaking oil is seeping and looking like another leak.

Plus..that will help the guy doing the work, because then things will be reasonably cleaner and easier to work on.

I'm not very helpful but I'll throw this out there. I'd Wait on the Rad flush until after you get the LIM done cuz you will lose your coolant when you do the LIm. It can be re-used but I would change out the t-stat when you do the LIM and then have the flush done after so all new coolant and they bleed your coolant system right after the flush too.
