try it with a rollbar in the way!

Dude, I am 6'5" tall, that just ain't gonna happen.

Muh belly is starting to get in the way nowadays also. It was a miracle getting my brake booster in without a freakin roll cage!!

Update....
After another hour of trying different wrenches and penetrating oil it wont budge! bolt. I think it turned a little but has that twisting feel to it. Don't what to break it. I need the car to get to work. So looks like I'm going to order a new flow kooler water pump, Timing chain, Fel-pro gaskets, ARP stainless bolts for everything in the front. And try again next weekend? Then if I can get a straight shot at it I can work it loose without breaking it. Awesome design FORD!!! nice job!

I think I got that bolt out with a 1/2 wrench cut in half. Was still a pain but I got it changed in about an 1 1/2 hours.

Tried the wrench cut in half. No go it's too tight. Has never been off since the factory installed it. I give up for now. It still works just wanted to do some PM. I'll go through the front of the motor next weekend and replace everything with ARP stainless.

That's what I did too, chopped down a 1/2" socket.

This may sound silly, but have you tried TIGHTENING the bolt? Sometimes a quarter turn tighter is enough to free a stubborn bolt so you can back it iff without issue.

Beware the ARP timing cover/waterpump bolt kit. I ordered one for the aluminum timing cover but somehow the bolts were the wrong ones. Just to let you know before you get into it. Dry fit everything and make sure the bolts fit good.

Thanks for the ARP warning.. ALWAYS something.. AS for tightening ya I tried but still feels like it's twisting and will break. I need to get everything out of the way so I can try to work it loose and if it breaks I'll be OK cuz everything is clear. It looks like I can grind enough off the WP and timing cover to get a straight shot at it with a with a allen for the next time only need about 3/16. Can't believe that Ford did not make that area more accessible.
I don't see how you can even get a cut down socket in there? There's only about a 1/2 inch and the wp/timing cover is 2/3 covering the bolt?
If it was taken off before and anti seized it would not be a big deal but after 24 years of not moving it's stuck and the lack of room is making things worse

Can you get heat on it?

heat might work if there is lock-tite on the threads. heat will melt it but good luck. Smart of you to wait till the weekend cause if its gonna break , its gonna break then your fugged. Might as well hunt down another lower intake/gaskets and have em on standby if your in a hurry. I know thats what id do if this was happening to me.

ok chuck,, we need you to make something like below. This part would extend the intake water jacket then the tstat housing would bolt to it thus relocating the tstat as well.

or maybe a 90deg elbow off the intake. that would lay the tstat housing horizontal. Stock hoses would fit, all you would do is cut off the last 90deg bend on the hose.

whatcha think?:D

on the dohc 4.6 i have, it uses a remote t-stat housing. i would assume you could find one at a junkyard, and use it on any car. you would still need to fix the leak at the manifold though.
