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

Is there a pressure relief valve somewhere?!?

I may just try another engine flush then. 😖. But alas. I have a ticking again so …. New lifters…. Which will open the block anyhow.

Yea, best i could anyhow, used air, even engine cleaner when everything was apart then air again. It has to be that tho. Lord mercy. Is there a way to do that without taking the whole thing apart…. Again.

Right, so, i installed all the bearings, i pushed in all sliding around…. This is gonna be dumb….cause I'm pretty sure i know but i second guessing myself these days—-but the holes, journals, line up themselves do they not? I know….. i laid them out in order and put new ones back in just like i pulled them out. One goes top the other bottom. One half has the hole… the other doesnt.

I'm reading this right now give me a minute, but yes. it has the sound of ticking again. The old ones were fine just worn down to the brass look. When i went back in… AGAIN…. (Yes i changed everything twice 😖🙄 long story tracking ticking, which eventually lead me to rebuild cause i found rings on 6 broke) they were fine.

I also want to say…. I put new cap on… still blowing out. Today. The video is pre oil pump, and the oil shoots higher than that.

It geysers out of all of them at 8 ft no joke

Well, the gauge in it says 35-40….. but i think its higher than that

Ok. Ive done everything I can to fix this. I rebuilt the engine, rings, piston heads, rod bearings, main bearings, seals, push rods, lifters, rockers, valve cover mods, oil fill cap mods, oil pump, vaccuum hoses, spark plugs, i drive this truck 5 miles….. its like weak. So i order from trevor waiting on new injectors. MY biggest problem is the 2-3 qts of oil blowing out the oil fill cap in just a 5 mile ride at roughly 45-50 mi an hour. Ive checked to see where its leaking from several times…. Its all from the cap. The ccv is not stopped up. I pull the hose and its sucking. 🤦🏻‍♀️😖. I had a friend do a compression test… he said everything was fine. Sooooooo, i will say the oil shoots 8ft literally from all the rockers. And I assume because of this its just hitting the hell outta that oil cap. Please help

I read somewhere bout new injectors for the jeep that were volvo? I noticed after my rebuild my 88 is still stuttering and wondering if i need to replace injectors…. And was gonna do the volvo thinv if someone could tell me exactly what to get for 88 4.0
