Well these things never end. My brother decided to have the same guy that adjusted my lifters change his intake manifold gasket, and it was a nightmare. First off he suposedly changed a hose that was leaking.

Apparently he thought this was it, and he probably thought that he would charge him 300 bucks for this. Then when he started the car back up later on in the day and noticed it leaking he had to rush to get it done. And left the engine compartment completely filhy. The reason we think this is because, he said he could do the car in one day. It took three days. Pictures will be uploaded later... Well once he finally changed the gasket he started it up and, he said it was making noises. He also told my brother that "There is a lot of sludge in that motor", and it looks like he dont change oil in the car.

So then he added oil, and started it up and the noises were better. So he then thought he could put tranny fluid in with the oil to clean and loosen up the lifters, and whatever was "gumy" inside the motor. The lifters were ticking so he dumped some tranny fluid down the crank. Well when that didn't fix anything...what suprise... he took the flywheel cover off thinking something could be amiss down there. Well coincedentally when we got it home it was about a quart and a half over full hmm... and looked black, with a foul smell.

He did have some low end noise, it sounded like bearing knock, but wasn't as loud as when my car threw the bearings. We changed the oil and dumped two quarts of SAE 40 down the crank with the drain plug out to try to lubricate the bearings and clean out the tranny fluid.

He filled up with Castrol Syntec 10w30. The bearing noise is gone, but under driving conditions and at in park at about 2 grand the lifters are clattering like mad. Can these be adjusted or is he SOL and going to have to get new ones?

I just love this guy and really regret taking my car to him after he told my brother "yeah that motor came out of a truck and isn't the right motor" People like this I think should have their hands cut off and not be able to work on cars ever again in there life.

Any suggestions? I told him to change the oil again in about 50-75 miles, and see if that helps the lifter clatter. Anything other then that I am out of ideas. I am sure we could adjust them/and put new ones in, but how much work is that?

The car just went down to Bowling Green, and back with no problem. The engine made no noises, and was very strong. He changes oil, all the time, and runs good oil. What can we do. Oh by the way the car has good oil pressure.
 
its not hard to adjust lifters, I prefer to do it hot and running. get yourself an old valve cover and cut the center out and a set of "valve adjusting clips" from a speed shop. When the engine is hot swap out the valve cover and put the cut out one on, put the clips on the rockers, then with the engine running back off the rocker arm till it "clacks" then tighten 1/2 to 3/4 of a turn.
thats all there is to it. I'll try to post a picture of my cut out cover.

geez, sound like a guy i took my '65 to last summer. I know that a lot of the mechanics in most shops nowadays don't really seems to know much about the older motors. Unless they can plug it into a modern diagnostic machine that tells them what box or chip to replace they are lost so I asked around to a lot of people for who they recommended for a guy that knows the old stuff. A number of them recommended this guy who is an old-timer and ex-hotrodder and ex-dragracer. So I take the '65 to him for oil / oil filter change, adjust the valves, check the carb for proper adjustment and most importantly get my timing down correct as it's never been quite right since I got the car. 2 days later he calls and says the car is ready so I go over to pick it up. It started fine and sounded fine so I paid him and left alomt $300 poorer. Pretty expenive to me but I figure if he got the car running right it would be worth it. I'm about 4 miles down the road and the motor is now warmed up. I come up to a stop sign and realize that now the car would drop idle down below 1800-2000rpm instead of it's correct 800-900rpm. I pull over and call the guy wanting to immediately return the car to him to have him fix it (it's now Thrus evening around 7pm) but he said no, he was too busy for the weekend and to keep it until Mon than return it so I do that. Drop it off again Monday and now THREE days later he said the car was ready so i go pick it up again. As I'm about to pull out he hands me an invoice for the 2nd shop visit. I just take it and throw it on the seat figuring i'll deal with that business later. Why should I pay him a second time to fix what he should have gotten correct the first time around and ended up actually making the car run worst than when I dropped it off? So I leave his place the second time and guess what......... SAME PROBLEM!! :mad
I got to the same stop sign as on my first return trip home and the idle again won't drop below approx 2000rpm. It only did it once the car warmed up same as the first time.
I ended up having to take the car elsewhere to get them to fix it correctly.
The first mechanic than had the nerve a few weeks later to call me to find out where my check was for the second visit that I never sent him. He wasn't too appreciative of my response to that to say the least!
 
It is possible that when the guy took the intake off some crud got in the lifter galleys and is causing them not to work as they should. If it were my car that intake would be back off and I would be looking in there for signs of stuff plugging the lifters. Just my .02

Yeah well we just started it up again today and the low end knock is back. I just don't have a clue how this happened, it ran great taking it over to his shop, and now all of a sudden all these noises.
 
Are we talking about roller lifters here? Kinda off specific topic but is it possible for the rollers on the lifters to seize?
 
here is the cut-out valve cover not too pretty, but it keeps the mess down:

here is are valve adjusting clips:

they clip on the pushrod end of the rocker arm to keep the oil flow down some.

FYI if you don't have center bolt valve covers it did not come stock with roller lifters
