For the same reasons you're likely to need a replacement, you're NOT likely to get a good used one. I meant to SHOP for a new EGR tube before messing with the old one - so you know how hard they are to find, and how much they cost.

Ohh I see! thanks!

Test it before throwing parts at it but you seem determined.

ericantonio

Haha, not really that determined. I just like taking things apart and putting it back together again. Half of me says "just get a new engine and parts" and the other half says "I know you can probably fix this". I have the dreaded "main seal leak", not bad like every 3 or 4 weeks I put a little bit more oil in it. Compression not so bad according to my mechanic who installed my timing chain and water pump. But when I replaced the harmonic balancer, I was able to crank the engine with a wrench. They say it should be pretty hard to do that if the compression is good. And I still get the DREADED ping ping ping or is it tika tika tika tika when accelerating. And still once a while, it bogs down when accelerating after slowing down to 30 or so. Just little annoying things like that

If you like taking things apart, take up junkyarding as a hobby. Then you won't hurt your truck, but you can learn, and collect old parts, which can be lucrative if you know what to look for.

I was just thinking the same thing!!! How about that. I just checked the website and there are like 4 of similar years nearby Parts/Pick.

I like checking once a while for a new bench seat. Since this used to be a work truck, almost all work trucks have a rip in the driver's side cause it's usually a big ol overweight guy sliding in and out of the side of the truck and rips up the side of that bench

I know this thread is old but figured it might help the next guy working on this.

The EGR tube is connected at two locations via inverted flair nuts. The top is connected at the EGR valve by the upper intake. This large nut is 27mm on my 1992 ford f150 4.9L. The other end of the EGR tube is connected to the exhaust manifold. On a V8, both the nut & the adaptor are 32mm; on a 4.9L, the nut is 27mm but the adapter is still 32mm.


Lower connection of the EGR tube on my 1992 4.9L. (This is what it looks like after you snap off the tube trying to remove the upper nut unsuccessfully.)

Now after snapping the EGR tube off I decided that I needed to replace the EGR tube assembly. You can see how the lower nut started stripping due to unsuccessful removal attempts.

I realized that the nut is stripped and would not come undone without splitting or grinding off (and potentially damaging the exhaust manifold). Since I could not remove the ERG nut from the exhaust manifold I decided the easiest fix would be for me to simply find a EGR tube and exhaust manifold assembly from the junkyard and swap out the whole assembly.


Found another 92 f150 at the junkyard. This is halfway through the removal process.


Took me 2 days but I finally got the assembly free from the junkyard.
