fiddlermj Posted Saturday at 02:37 PM Share Posted Saturday at 02:37 PM 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 Link to comment Share on other sites More sharing options...
89 MJ Posted Saturday at 03:53 PM Share Posted Saturday at 03:53 PM What is your oil pressure when it’s running? Link to comment Share on other sites More sharing options...
fiddlermj Posted Saturday at 08:20 PM Author Share Posted Saturday at 08:20 PM Well, the gauge in it says 35-40….. but i think its higher than that Link to comment Share on other sites More sharing options...

Might want to check it with a mechanical gauge. Is it a geyser out off all of the rockers or just a few of them? Link to comment Share on other sites More sharing options...

It geysers out of all of them at 8 ft no joke Link to comment Share on other sites More sharing options...
fiddlermj Posted Sunday at 02:02 AM Author Share Posted Sunday at 02:02 AM 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. Link to comment Share on other sites More sharing options...

At least its all rust proofed. So somehow, it seems that the lifters are getting way too much oil or possibly that the lifters are diverting all of their oil up through the pushrods. I'm betting the first option though. Does it sound like it has a lifter tick? Being that it did it with the old oil pump too, I think we can safely rule that out from being the cause. I found this on how the oiling system in the 4.0 works: Quote From the FSM: LUBRICATION SYSTEM A gear—type positive displacement pump is mounted at the underside of the block opposite the No. 4 main bearing. The pump draws oil through the screen and inlet tube from the sump at the rear of the oil pan. The oil is driven between the drive and idler gears and pump body, then forced through the outlet to the block. An oil gallery in the block channels the oil to the inlet side of the full flow oil filter. After passing through the filter element, the oil passes from the center outlet of the filter through an oil gallery that channels the oil up to the main gallery which extends the entire length of the block. Galleries extend downward from the main oil gallery to the upper shell of each main bearing. The crankshaft is drilled internally to pass oil from the main bearing journals (except number 4 main bearing journal) to the connecting rod journals. Each connecting rod bearing cap has a small squirt hole, oil passes through the squirt hole and is thrown off as the rod rotates. This oil throwoff lubricates the camshaft lobes, distributor drive gear, cylinder walls, and piston pins. The hydraulic valve tappets receive oil directly from the main oil gallery. Oil is provided to the camshaft bearing through galleries. The front camshaft bearing journal passes oil through the camshaft sprocket to the timing chain. Oil drains back to the oil pan under the number one main bearing cap. The oil supply for the rocker arms and bridged pivot assemblies is provided by the hydraulic valve tappets which pass oil through hollow push rods to a hole in the corresponding rocker arm. Oil from the rocker arm lubricates the valve train components, then passes down through the push rod guide holes in the cylinder head past the valve tappet area, and returns to the oil pan. This has me thinking that possibly the main oil gallery is either somehow larger than it is supposed to be or that the other oil galleries coming off of the main gallery are partially blocked. No clue how that is possible though. How did the main and rod bearings look when you changed them? Link to comment Share on other sites More sharing options...

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.

fiddlermj Posted Sunday at 03:51 AM Author Share Posted Sunday at 03:51 AM 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.

89 MJ Posted Sunday at 04:10 AM Share Posted Sunday at 04:10 AM You are correct. I get why you’re second guessing yourself, this is a super strange issue Link to comment Share on other sites More sharing options...
AZJeff Posted Sunday at 05:24 AM Share Posted Sunday at 05:24 AM Oil blowing out of the fill cap would be due to crankcase pressurization. Oil geysers from the pushrods would imply some serious blockage in the oil delivery system to the crankshaft, resulting in most of the oil going to the lifters, who, in turn, pump it up to the rocker gallery. Did you clean out all the cross-drilled holes in the crank that feed from the mains to the rods? Did you also make sure all the feed holes from the main oil galley that feeds the mains was clean?

fiddlermj Posted Sunday at 02:12 PM Author Share Posted Sunday at 02:12 PM 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. Link to comment Share on other sites More sharing options...
fiddlermj Posted Sunday at 02:58 PM Author Share Posted Sunday at 02:58 PM I may just try another engine flush then. 😖. But alas. I have a ticking again so …. New lifters…. Which will open the block anyhow. Link to comment Share on other sites More sharing options...
89 MJ Posted Sunday at 03:20 PM Share Posted Sunday at 03:20 PM I’d try dumping a can of sea foam in the oil and running it at varying rpms for a bit. Maybe 20 minutes or so. Maybe that’ll help, maybe it won’t, but it’s worth a shot. Link to comment Share on other sites More sharing options...

89 MJ Posted Sunday at 07:41 PM Share Posted Sunday at 07:41 PM That would most likely be built into the oil pump Link to comment Share on other sites More sharing options...

Ran it for bout 30 minutes. Drained oil…. Metal shavings. Guess there is something to the bearings Link to comment Share on other sites More sharing options...
