Body Damage is Cool
Hey guys, it has been a while.

Saturday while driving home and at about two miles away al of a sudden POOFFF A big white cloud of smoke behind me that smelled like sweet candy and a misfire.

It has to be a head gasket, it did not overheated or nothing and it made it home fine.

Well, I only trust my vehicles to a mechanic friend of mine for this kind of "big" jobs but this time he is nowhere to be found. Given that I had to pull my 88 SWB from semi-retirement while I work on the turbo engine, I will have to tackle this job myself.

I have order the gaskets and it is recommended to replace the head bolts, right? At the same I will be replacing the valve seals as it is showing the symptoms of that too.

Any other recommendations?

Thanks,
Javy

Hello Javier,
nice to see you posting again. Well, how recently has the timing belt been done? If you have done that and recently along with the water pump, I would just keep that stuff. But if it has been a while, I would think about doing that along with the head gaskets.

Javy, if you want, I will mail you my Leslie Valve Keeper Removal tool if you want this to be done easily. Once you finish you can ship it back.

Hi Jay,
Indeed the water pump, timing belt, tensioners and all other gaskets and seals are about 6 months old.
Borrowing your tool would be awesome, I will take extreme care of it.
My main worry is to keep the timing belt aligned and that nothing gets out of whack, the rest should be straight forward. I will take the precaution to mark everything. Did you set yours to TDC before disassembly?

Hey Javier,
Send me your address in a PM and I'll ship it your way.

No I did not set it to TDC before disassembly although I wish I would have thought about that, it may have made my job easier. You may consider a new upper intake gasket as it is a flattened metal gasket with ridges that get crushed down when you torque the upper intake.

The engine will be fine as the 3.0L SOHC is not an interference engine so I wouldn't worry about keeping the timing belt aligned. Of course it's critical during reassembly, but I wouldn't sweat it during disassembly.

I'll wait to hear back from you about the tool bro.

Jay,
Pardon the late reply. I ordered the full set and it comes with all the needed gaskets.

I sent you a PM with my address.

Thanks again.

I am in the process of doing head gaskets also. I tore it down yesterday. I only need to unbolt and remove the heads now. I am planning on doing everything including the bolt replacement. When I did this over 100000 miles ago I did not replace head bolts, but since this is the 2nd time I think it is due.

I have done 4 head gasket jobs on 3.0 monteros. I reused the bolts on 3 of 4 jobs. The only one I bought new bolts was the 93 where the previous mechanic did not put the thick washers back under the bolts.

Also don't worry much about setting the timing in the correct spot on disassembly. The cams will spin under spring pressure at some point. Just watch your fingers when do.

An impact is good for taking the cam bolts out. You should do the front end seals while you are in there. Also check the size of the seals before you take out the old ones. Some aftermarket ones do not fit.


I just want to tell you both good luck, and we're all counting on you.

LOL, and I thought I was the only one, ah?

This engine has 276k miles and the head gaskets were done by the Mitsubishi dealer when it was 135k miles, I know so because it was my wife's uncle vehicle.

So far no surprises, everything going smoothly as pie. Just found one of the exhaust manifold's bolts on drivers side, one on the front, was broken and the dealer did not bother to fix it, had to be them as they have been the only ones that have been so far. Also maybe one or two missing not important bolts.

I ordered a full gadget set from www.rockauto.com together with a new set of head bolts and I am glad I did because I found that on the driver's side from front to back the second pair of bolts had the, how can I explain it easily, the shape of the hex shape messed up. I notice that if they used the hex cube (10mm by the way) like the one I got from O'Reilly, the hex part is an out 1.5"long and the part that connects to the ratchet (I'm tired and can't think straight) hits the rocker arm shaft's tower. I had to use a 3/8 Allen key.

I am taking pics as I go because men there are bolts every where. I will post some pics tomorrow.

New head bolts are not necessary. However it has been my experience that reusing head bolts has disastrous outcomes. I'm lucky that way I guess. LOL.

I see you got new bolts. Good for you. I'm always strongly recommending to people to get a new set as opposed to reusing them.
