I would like to know the actual failure rate of flat tappet camshafts if that could actually be compiled. I know of several car guys that have never lost a cam. Most of them have not built many engines and theirs have mostly been fairly mild engines. I lost 2 Comp Cams in a row in 2006. This...

The next week, I installed a new 100 psi. oil-filled mechanical gauge. I swapped the Fram filter for a new Wix filter, half filled with oil. With my wife again turning the engine over with the starter, I spun the oil pump with my drill motor. The oil pressure pumped right up to 75 psi. and...

The plot thickens. After cleaning off the rh head, I backed the hold down hardware off and rotated the shaft. NO CHANGE! From my research, having the 15* offset is correct. These shafts along, with the double holes, there is no offset. I don't see anything ugly up on the head, like metal...

So tell me how the shaft gets oil with no hole in the top of the shaft? Inquiring minds want to know. Kim

Did you perhaps Connect to "Batt+" FROM the Alternator along the way? Instead of connecting to fuse block 12V "Hot in Run" circuit? If so, that's gonna send AMPS over Volts, & Will cook a wire.

Let me try to put a finer point on it. I assume you know what valve float is, is that correct? It is simply when the force of the valve train (mass x acceleration) is greater than the force of the valve spring. Essentially, the lifter loses contact with the cam lobe around max lift and then...

You did not have the problem when you took it apart. There is your clue. Something is being overlooked.

Replaced oil sender on my winter beater 95 Wrangler. The guage pegged on high, no strange noises besides the normal strange noises. It literally took longer to go get a new sender than actually replacing it. 30 minutes to go to local Napa, <5 minutes to change it. Oil pressure on guage back to...

Yup I’ll add that I’d have no reservations about running a HV pump in KD’s combo. If the thicker oil didn’t get me where I wanted to be, I’d slap a HV pump right on there. Under 40psi in a performance build BBM at cruise is lower than I’d like to see. As for cold start oil pressure…….. on a...

I'll have to go back and look at my notes or even through this thread. I did pull the spring from the last oil pump I had. Posts 798, 831 and 833 I mentioned this. The pressure I am getting now matches what I had back after I swapped in the purple spring. It has not dropped. THIS is the...

Yeah that wasn’t a good picture, I was tired and just quickly snapped one. I drive this car pretty regularly with no issues, it’s been as far as Lubbock, 230 miles, I thought hay 90 miles isn’t a big deal for it. There’s always that 1 trip. I think the distributor o ring messed up, and...

Took the 63 Polara to a show 70 miles away. Checked oil before we left as I always do and it was fine. Car ran fine on the way there. On the way home my wife said she thought she smelled oil burning at a traffic light. I figured it was another car in front of me. Noticed slight vibration...

Wouldn't the appropriate questions to ask about oil filters are: Micron rating (particle size filtered); maximum flow rating in terms of gallons/minute or liters/minute or some quantifiable unit of measurement; pressure drop (pressure) or flow loss (pressure) at maximum flow; canister burst...

...the intake roller #2 on the passinger side had pushrod jump out of lifter and lifter was 1/2 way out of the bore so when cold and no oil pressure it slipped down in place. So when engine warmed up lifter pushed out of hole by cam shaft and oil pressure did the rest pushed it up more and oil...

There's recommendations of heavier oil, big pumps, and I wouldn't do any of that. 10w30 " might" be a little light on a worn engine but not a deal breaker. I have a stock 440 with a stock pump with red spring, stock bearings and clearances, stock valve train and all. I've done 10w30, straight...

First assume we have a properly working gauge. Let’s also assume the inlet side is not sucking air. Oil pressure is low at idle because the pump can’t move enough volume to build resistance to flow. Why? Thin oil, internal leaks from sloppy lifter bores, large bearing clearances. Shimming the...

I've always thought that adding a zddp additive to oil was overkill and maybe even harmful to oil that was already formulated for a reason. This article/thread proves that adding zddp to any oil can deplete the amount of pressure that the oil already had in the original formula. (I copied just a...

It's a great picture. Remember, these cars needed maintenance back in the day when they were new. Ten thousand miles was a bunch years ago. You're all good!!

‘This’ problem I guess would be the oil pressure dropping when I’m driving after a while. I guess I assumed it and the stalling when first starting up were related because they started happening at the same time. The other stuff I said was just info to maybe help inform a guess as to what could...

There's no telling how many oil filters, all brands, I've used thru decades of tinkering and never had one kill the pressure. I hope you get a chance to cut all 3 apart and find a cause. Glad your running.
