Tired Mule - Toyota 4Runner Forum

hopdup · 03-27-2014, 10:24 PM

So I picked up a 2001 4Runner from my cousin. Thinking it needed an engine swap. Rad went, overheated and warped the heads.

Old engine out

Picked up a new/used engine with 94k on it. Getting ready to do a T-Belt, Water Pump, Drive Belts, Valve Cover Gaskets, Rear Main Seal.

I couldn't resist, I had to slap some headers on it. Thinking now's the time to do them.

Good time, indeed!

Got some parts in today and a lot of work ahead of me.

Also, does anyone have experience with solid engine mounts on a 4wd. I have installed them on cars in the past, with a poly trans. mount. I'm thinking of welding the factory mounts solid. I have seen Addicted Off Roads poly mounts. I imagine there isn't much deflection with them. Only thing that scares me is the torque from the engine is now taken by the trans. mount. Thoughts?

why would you want solid mounts?

My cousin borrowed my 94 Bronco years ago and put it into a ditch. Ass$%le!

I'd consider replacing the FIPG on the oil pan and the oil cooler gaskets as well.

They provide crisper throttle response. Also eliminate torque loss and binding that come from excessive engine movement.

I will be resealing the oil pan. Although it's not that hard to lower the diff and reseal. I've done it a few times at work.

with increased vibrations.
its not a racecar, or dedicated wheeler, right? it will be a daily driver?

theres no way I would deal with solid mounts on a street rig.

What headers are those??

Nevada - you make a great point. The stockers are going back in.

J.B. - The are OBX. I picked them up on ebay $300 shipped.

A friend has solid mounts on his Tacoma and says it will vibrate your fillings out when at idle, but is great when shifting/accelerating. His isn't his DD though. I'd probably recommend not doing it as Nevada said as it would be uncomfortable for a DD.

Why does no one put a flex joint on any of these headers?
My Doug Thorley ones don't even have one... and guess what.... they're cracked....

The outlet flanges use a ball gasket and a round seat on the y-pipe. If you look close you can see the springs bolts. This allows for slight movement. I might weld in a flex section in between the frt. and rr. cats.

Im liking the headers, but I have to ask, did you use the gasket that came with them, or a different one. Because ive heqrd nothing but bad news about there gaskets. The headers are quality themselves, but only when paired with a better gasket.

I used factory exhaust gaskets on the cylinder head flange. Also used the factory locking nuts. The only gaskets I used from the kit were the donut gaskets for the y-pipe. I'm kinda on the fence with those. They don't look like they will last very long. I could mount the y-pipe with small crush gaskets from Toyota then weld in a flex joint. I'm leaning toward the latter.
