Thread: Roger's LARS Mis-Adventure 2014

Tweet

To stop any further diversion/hijack of Don's "Roadtrip to LARS" thread I'll start one for more details of what I find with my engine as I get into it. To summarize the SOE leading to the end of my 2014 adventure, at 198 miles from home, traveling at 80mph down I35 toward Duncan, OK my oil pressure dropped to zero and the loud rumble of the exhaust became a raucous clatter. Dumped the clutch, hit the "OFF" button and coasted to the side of the road at MM 9, nine miles from Oklahoma and about two hours from Don's BBQ event.
A few phone calls, an hour wait for the flatbed truck (AAA told them MM 2, south of their shop at MM 4 ) and we had it loaded for the 3.5 hour trip home.

The car's in the barn shop, sitting beside the '32 Roadster, waiting for a detailed plan off attack. At this moment I'm thinking that the problem has to be with the oil pump shaft, either sheared or dropped, but I may follow Jerry's advice and pull the intake and so that the distributor can come out to look at it from the top first. All that costs is a set of intake gaskets and some time... I'm not sure at this point if I can drop my pan without pulling the tie rod, but that's a minor hassle. Will know more soon.

Well now..................that sucks!
Hope it's not anything real catastrophic.

Motor is not going to be hurt with only 5 miles of no oil. Not making the trip is disapointing. Hang in there and sleuth out the problem.

Sad to hear. Hope you get it back on the road simply, affordability, and soon.

Bummer, Roger, an event which we all dread but are aware of the possibilities. Glad you got it home without "TOO" much hassle and hope that the fix is in your favor also. Good Luck

Sorry to hear, Roger. These things are frustrating; hope it's nothing too serious.

Roger saw your post on Don's page and was sad to hear of your bad luck with the coupe... was looking forward to meeting you and the other guys but looks like that will have to wait for us.. hope the problem is a small one and you're back on the road soon...

Roger sorry to see your misfortune. Hopefully it's not too seriously damaged. Good luck with it, Ryan.

Sorry to hear about the engine travails Rog, nobody wants to have to deal with that.
Hopefully its minor & can have you up & running soon to enjoy the rest of summer...
Let me know if you need help brainstorming or whatever, sir.

You are not the only one that has had his car hauled home. It happened to me about twenty years ago coming back from an event. Luckily, I was only 5 miles from home; unluckily, it cost me an engine. Hope your luck is better than mine was.

I decided to go in from the top first which entails pulling the whole EFI intake assembly.

When I pulled the distributor it looked normal, but when I looked up into the end it wasn't clear. A couple of taps and the top of the oil pump drive shaft slid out.

I'm dropping the pan now to check the pump and see if it seized, or if there is any indication of why the shaft sheared. Normally if the pump seizes the shear pin on the dizzy drive gear goes.... Hoping that everything's OK, and a new shaft, new pump and some gaskets is all that's required.

Roger, are you going to pop some bearing caps to see what the bearings look like while you're in there? That definitely stinks. Hopefully everything else looks good in there.

Roger, the shop that did my engine advised me to not use that style of pump drive. I handed it to them and the assembly guy handed it back and said it'll break just below the distributor, said he's seen a bunch of them break there. I installed a stock one and "we" chose to keep the bearing clearances a bit on the larger side to flow more oil. My O.P. runs about 40 when hot.

What's the oil look like? I would also think it prudent to look at a few of the bearings to check for damage and see if there was a film of oil left.

Something caused the oil pump to seize. It moves freely with the cover off, and with the cover on with bolts loose but tighten the bolts finger tight and it takes a pair of pliers on the shaft to turn the pump, and if the bolts are torqued the pump locks. Ever seen a pump shaft twist like this?
