my 03 hummer h2 with a 6.0L V8 LQ4 with 250,000 km on it seems to have a rear main seal leak or a oil pan gasket leak. Most likely it is a rear main as i noticed more people on the hummer forum having a rear main leak.
I noticed the leak about a year ago and it barely made a difference on the oil level, and then winter came so i never really looked or checked but everytime i would check the oil level it was always in a good position.
it is summer now, and i guess maybe the hot weather is making the leak worse but i notice more oil under my vehicle now compared to before.
i recently checked the oil level and it was about 1 quart low so i quickly filled it up. i last had the oil change in february and i have already put 5000 ish km's since february so it seems to lose about 1 quart over 5000 km or 4 months ish.
the thing is that i am parking this vehicle most likely by next january, and i dont want to spend $1200 on labor etc.
so i wanted to ask, what are the chances that if it is the rear main, that it just completely blows out and drains all the engine oil out within seconds?
my plan rn is to just keep it like this and keep adding oil and if i notice that i am adding way too much or if it starts to leak way too much then i obvs have to do something about the seal.
i was also thinking of running blue devil rear main sealer or at 205 resealer but i also heard that gm engines use a teflon rear seal which wouldn't be able to be "bettered" by stop oil leak products. so i am not too sure about that, any way i can actually find out what seal i have in the truck? its a 2003 and it is a 6.0 LQ4 engine unless I am mistaken on the engine model.
thanks!
