fiddlermj

so. I'm awaiting fuel pump etc etc. but this has been happening for a bit now. I replaced fuel injectors with the good ones from guy on here… and.. a fuel filter… just curious what yall think

Sheeeeesh. I'm gonna prolly need a whole unit considering the one in it is a cherokee

Thank god for dear old cruiser’s sruff. Had to use this today make sure my injector plugs were in order

I'm looking for the best source to get a new fuel pump for my 88 comanche. I ordered on ebay but they lost it. Then a friend mentioned something bout a Bosch? Can someone just point me to the right fuel pump replacement

Yea the whole thing that goes in tank

So is there a replacement fuel pump for 88 comanche 4.0 that is like the original? I know some years ago there wasnt, but just curious if the market had finally made one that reads true.

I had a ring busted when i decided to rebuild this thing. I really think…. Just trash and stuff did this. This is po girl build/hi class hunting truck. I'm going to clean and flush it best i can and polish the crank… and see what happens. I have a donor…. So…. Prolly gonna kill this one then….. swap.

Umph. I hear ya.

Ah i called him. He just measured rod crank part not the main bearing part. Where #3 was

And the pieces… now. When i changed oil it had like a finger nail clipping sizes. Some of that is like zinc additive you see in oil

Ok i went to shop just now. And took pics. 20-30 mi on these bearings.

Yea its a good question on that micing. I wasnt there. Soooo….. I'm not sure. I myself didnt mic it. He just said its fine. But now you got me questioning. Yes it was scored. Ill take a pic of all of them in morning. Yea i found the shavings like fingernail clips in oil when i changed it, which is why i removed the bottom. There is a nick in the crank. Not bad that a polishing can't fix. Ive been brake cleaning and air blowing all day. But the thrust has a copper streak all the way. In morning ill post pics of everything

I had a machinist friend come mic the crank its fine. The shavings were coming from the thrust bearing, after i checked the #3 rod bearings i pulled the mains to check and yea….thats the source of shavings. Sooooo. I'm brake cleaning the hell outta all the journals and shooting air thru em. The cam looks good. No ate up spots or pitting etc. i guess maybe the shavings clogged the journals to cause that geysering?!?

Well. I dropped the oil pan. Plasticgage all the bearings (except number 3)… all were .001” except when i got to #3 …. I noticed fore I did it that the bearing did not fit snug in the cap. There is “give” to the top edges.. do i need to get an oversized set… for this one or…..i will plasticgage in morn…. But just wondering

So. I dumped whole can (yea i know) seafoam in…. Ran it for bout 30 minutes. Drained oil…. Metal shavings. Guess there is something to the bearings
