86.5 7MGE Problems

cre · 10-19-2009, 06:11 AM

I'm going to be disgustingly blunt here... if you don't like it, I'll apologize in advance... I'm sorry.

The parts store guy is a F@#$ing idiot and you really need to find a mentor to help you out while you learn your way around the engine bay.

There is NO WAY a running engine will get WET oil on the plugs much less soak the THREADS which happen to be outside of the combustion chamber! NONE! The parts guy is an idiot and you've got leaking valve covers or the bolts which hold down the No3 gasket.

Wet oil around the plug wires can cause shorts to ground and a heavy miss... the fact that replacing them makes it feel better for a while is because each time you pull them you're dumping all the oil that was surrounding them into the cylinder and thus eliminating the real problem for a little while.

A plug which has seen burning oil is black, but it's dry.

No worries CRE, you seem like you know way more about the Supra then them and I'm not calling you wrong on this, because what you said makes more since than anything any of these parts guys has been telling me. I still consider myself quite new to the Supra, it's become a headache at times, but I still love the Supra it's an awesome machine. Hey, since your in Denver also would you care to be my mentor?

I'm not up for mentoring... I haven't the patience for it. I may be persuaded into coming over and having a look and helping you figure out where to start though. PM me your email address or phone number.

If you haven't already, order new valve cover gaskets. They're not that expensive and I'm positive that's where your oil is coming from (it's VERY common). Even if the gaskets are still soft they compress over the years and will fail to seal no matter how hard the covers are tightened (NEVER over tighten the valve cover bolts! The covers warp easily enough and then you're screwed.). The valve covers are supposed to be tightened at 22 INCH lbs... NOT ft.lbs. If you don't have a torque wrench capable of such fine measurement then use a screwdriver and only tighten them hand tight. Some people like to switch out the phillips head screws for bolts; that's fine, but you still need to make sure you're not over tightening them.

Ok sounds great I'll PM you right now. I replaced my value cover gaskets in Oct last yr that's one of the first things I did to the car is a tune up to include replacing the value cover gaskets. I think that when I went to replace my No 3 gaskets I used the wrong gaskets all together so I'm going to redo them with the part number I got from IHATEHACKS thread just in case so there will be no more second guessing on it.

Personally, if you've still got the No3 gasket I'd use it. Just clean off the dried up rubber around there the big bolts go through so it's bare metal and then put some RTV on both sides and reinstall. Those plugs don't really see any pressure worth mentioning so if you don't want to keep the gasket then you could just put RTV on the plugs and be done with it. I'd keep the gasket though, it still serves to keep larger debris out.

I do understand why IHATEHACKS didn't replace it with a new gasket though.. they're damned expensive. The thing is that they're supposed to seal along the sides too. I keep thinking that sometime I'm going to build a template and cast a silicone piece to laminate to the old gasket.. I could do that for half of what Toyota wants for it and get the same seal and... COLORS!!!!

No I threw that thing away to the trash when I put in some plastic gaskets from Napa but they weren't as snug as I would have liked them to be.

Tisk, tisk... well, if they're not sealing they'll leak a bit and it will also cause a vacuum leak. Double them up if need be. Me, I'd toss them, take one of the plugs to A & A Tradin' Post on Broadway and buy a few nice fat O-rings which fit the plug just firmly enough.

I hope you never work on a car ever. especially if you dont know what spark plug problems are...
If a plug is wet. that means one of 3 things....

bad valve covers (most likely not)
blown head gasket and oil getting into the combustion chamber
or piston rings are shot.

maybe you should watch who u call names at a parts store especially if your the one with the issue not knowing whats going on... just saying.

Dripping wet when you pull them? Not a chance in hell... not unless there's a hole in the F$%^ing piston... ALL of them in this case. An engine with completely shot rings still creates enough blowby to ensure that most of the oil that does enter the cylinder is burned. This is a VERY common problem too. Additionally, I've been to the OP's place... it IS his valve covers.

AAP, did you even LOOK at the OP's pics?

See the oil on the THREADS? That alone completely negates the possibility of the oil coming from inside the cylinder. Seesh...
