Did you pull any main or big end caps off whilst you had the sump off?
hi efi , I didn't.Should have really like you say,thing is think this motor may have been modified, has a Swaymar manifold ,Holley etc so if re-ground crank ,so on would need plus sizes of mains & so on...... Lost heart in it a bit. I only just purchased really & could see the sump had been off recently. I think they may have had an idea it's on it's last legs🙄

hi coupe, yeh had a look & check about ...strainer was clean & no cracks..... Pencil drive & pump didn't look that old,no wear on pencil drive at all. As mentioned above, think someone's tried not so long ago, had me fingers burnt with this one I think.

hi rebel alliance..... No none at all really. Little bit of light tappet noise.Really runs okay & temps fine now also. Probably completed 1000 miles now & the guage has shown no real oil pressure,just thought it was not working till I changed it & got a little oil pressure reading??????

I’ve seen Essex engines at 10psi hot idle go on for thousands of miles. You could probably get the pressure up by replacing the main and/or big end bearings. You can also boost the oil pump pressure a bit with a washer under the PRV spring (which is all the “high pressure” pumps are - essentially a stronger spring).

Yes, now you have mastered getting the rear sump bolts out :D

PS - I was adding to my post when you posted.

👍Big ends ....... What about the weight of the crank shaft & fly wheel on seals when releasing main bearing caps? Is there a trick or system to use when doing them scimjim

Never done it myself but I imagine if you loosen all of the mains bolts half a turn, you could remove one cap at a time and push the top half of each bearing out with the new ones?

The other main caps hold the crank and flywheel assembly weight, just do one at a time and use an old bearing shell to slide the top bearing round.

Done this on the Essex V6 loads of times, as long as the crank is OK then it will be fine.

My 6a had the wrong shells fitted which is why it had such poor oil pressure, the crank was STD size but the shells were the wrong external size...

One of the infamous “oversize standard reworked” blocks where they line bored them another 20 thou or so?

Never try and argue with an idiot. They drag you down to their level, then beat you based on experience.
