J&B, what type of engine, how many miles, and when and what RPM does it make the noise? You might want to fix that ASAP... My second 390 (first in the 73, it was the one that came in the pickup) was quiet and clean the day I bought it, the next day it had what sounded like a clatter at about 1400 RPM. Drove it that way till the late the next fall at college and tore it down. The noise was getting more constant and in more of the rpm's. Glad I did it to! I had a rod bushing work loose on the #7 rod and it was allowing the piston to rock side to side. Thankfully it didn't cause any wear in that cylinder but if I had kept driving it that way it would have eventually scattered and proably ruined the block and rod if I was lucky, possibly would have taken a head or heads, and crank among the more expensive things. Just a thought.

Motorcraft 15-40. I like the detergents of diesel oils for my dirty old 390.

Annihnlator , 390 , miles only God knows . to my belief it was rebuilt 2 yrs. ago and then sat for 2 yrs. before I bought it . lot of nice equipment on it .
I know it sat because I found bird nest in the duct work . ok , I believe past owner did not go to ,to much trouble when he decided to start it again . I've changed rod bearings , some good some worn . the knock is at idle coasting across the parking lot . the engine is tight , 20 inches of vacuum at idle and 55 lbs. of oil pressure cold , 40 warm . from past research and reading books , I guess 390's are notories for wrist pin knocks if not done just right . they say it should last . I hope , cause I have no garage to pull the motor . the only problem is , not being sure , I'm afaird to go too far , I hate break downs but a ford has never done that to me in 35 years .

I have never heard of FE's being notorious for wrist pin knock but if there is one problem prone area on an FE, then rod bushings can come loose if not done right. But all in all I don't think it is extremely common. If your a gambling man, you may be allright but who knows, I would try to find a mechanic that has a lot of experience with FE's and Fords in general as they have a tendancy to be a little quirky.

Lucas for wrist pin knock?

J & B if you need "Lucas stabilizer to help wrist pin knock" you have a sick engine and your fooling youself and wallet that different oil or "additives" will patch your problem. Use some "gray matter". Sorry to sound harsh but people who belive in Lucas products keep Lucas in business. Like power steering troubles, added Lucas and it takes one finger to steer, before it took three WWF people to turn the steering wheel. Bull s**t. Like Lucas stop leak sealer, when the solvents that swelled the seals boil off, the leak will be worse. This is ok for a quick sale to a sucker but not for a keeper.

Carl....=o&o....

Beemer , the stabilizer is not for the knock but for the oil . as you know , I'm sure , is that multi-viscosity oils have additives which cause the oil to break down sooner , also I live in a high humidy climate . I am only using the multi-viscosity for the cold weather start ups . tried all the other combo's of oil and this one seems to work the best until I can pull the motor for further research . " gray matter " ? non-potable water ? no thanks , that is not compatable with oil

most single weight oils use the cheap basestock.
