Not really. It requires a "smooth-ish" surface. It is rubber. It is compressed between the thermostat and the housing. It will seal just fine *if* the surface is less than optimum. *If* there is a minuscule amount of coolant seeping past between...

This particular rig is one of those very nice ones that seem almost original stock at first glance but with a lot of quality upgrades once you start to look closely. It has OEM manual steering right now, but I expect that retrofitted OEM PS or...

So? Mark...

From what I can see in these pics, those housing halves are totally serviceable. Clean the ugly off and drive on. Mark...

Customer picked up this '40 today. Called me when he got home to tell me he LOVED how it drove now, and that it totally ignored the ruts that used to lead it around by the nose. Mark...

I'm not sure what you're asking. It seems like you are asking... if you put a new sending unit and a new gauge in can you trust them? If that is the case, it's kind of like asking, if I put brand new tires on my truck are they safe to drive? If...

I installed the shims this afternoon, and broke for lunch. The rig is still in the shop. Gonna re-jet the webber back down to sea level standards before I pull it out. I'll take it for a test drive, but I have never driven this particular rig, so...

The only thing a Thornbird is good for is a dock bumper. I have run 32s (285s) on a couple of stock FJ80s with no complaints. Personally that is the largest tire I would install on a stock FJ80. IMHO the 3FE is just gonna be working to hard to...

Your gauge is lying to you. Your temp gun is showing that your engine is at normal nominal temps. (Dontr be afraid to reach in close and get a variety of readings from smaller, more precisely selected areas too.) Mark...

I've done my share of dumb things. But I have also seem my share of wrecked '40s. And talked with people involved with injury/fatality FJ40 wrecks. I would not operate a '40 without a roll bar. 1 inch ANYTHING is not a roll bar. I personally...

To answer your actual question... I just finished adding some 2 degree shims to a '78 FJ40 with OME suspension a few minutes ago. Rig was on the hoist to reseal the trany/TC, and while it was there I... Removed all four ubolts and both...

This picture is so very very much not today. I just happened to notice this thread because of the fresh post.And I don't think i've ever posted a picture of one of my M416s behind one of my rigs. I'm not sure I have any pictures other than this...

You may have a bit more noise between the gears unless you swap all the other gears too. By\ut you might not, and I doubt that it will be significant anyway. FWIW, you might try taking a wire cup brush on an angle grinder to that shaft and see...

A good undamaged shaft will swap in no problem. The teeth and splines on the shaft are not gear teeth so there is no concerns about differing wear patterns causing noise. Mark...

Hopefully, the handful of facts that I tossed out there along with all my pontificating, will be of some assistance and understanding of what you've got going on. 😉 Mark...

I see a charge for "grind lifters" on your invoice. I do not see anything about the cam. You don't "polish and grind" lifters. You resurface them so that the surface is as new and then you install them with a new or "reground" (made new again)...

I've been running the Scepter cans for 20-20+ years now I guess. I have about a dozen. I have used them pretty hard. The internal vent assembly broke on one of them, but it still works. Just does not pour quite as fast at full tilt. Still beats...

The rest of my first post... Other than the gauge, how do you know it is hot? Have you taken any actual temp readings? Based strictly on the info you have provided so far, my money is on the gauge being the actual problem. Mark...

The tab will interfere with the waterpump if you install the gasket backwards and it will not fit. Unless you do something stupid... like cutting it off. Mark...

The tab is SUPPOSED to be sticking out the back. Your picture clearly shows (in the mirror) that it is. Mark...

If someone wanted to install the head gasket backwards, they would have to cut the tab off of the back end in order to do so. The tab is there for exactly this reason. To ensure the gasket can not be put in backwards. Not an easy mistake to make...

I can't say that I've noticed any improvements in how the 2F runs. It is a 2F after all. I had a Downey header on a FJ60 that I swapped over to the FJ40, and the Downey was IMO the best of the headers available at the time. It eventually...

My experience with pre-cat 2Fs is that there is in fact a big difference between the stock manifold and pretty much any tubular header. Even on an otherwise stock engine, the difference was always notable. Mark...

3FE exhaust on the 2F is another option https://forum.ih8mud.com/threads/3fe-exhaust-on-2f-head.955034/

The thin steel tubes of an exhaust header lets more sound loose into the engine compartment that the thick heavy cast iron factory manifold. But I don't think this is what you are talking about? The exhaust sound that a rig makes.. the sound you...
