Saturday I out the valve covers back on and started the engine. It still has the problem on #6 exhaust which cause a miss, especially noticeable at idle. But overall the engine is running smoother. My guess is the valves were too tight after the oil pressure was boosted with the replacing the...

Thanks for the suggestions. This weekend I will take the intake manifold off and see what I have. I hope it's not too bad. I would hate to have to pull the engine and transmission out of the car. My son and I built this car together and now he has graduated and moved off on his own. Wish me...

If I did wipe a cam lobe. Does the engine need a complete tear down and rebuild. (i.e. new cam, rod and main bearings and de-glaze cylinders?

Thanks to all who replied. I have reset the valves. But I think I found the problem. While adjusting, when I got to the #6 exhaust I found the rocker arm floppy. The adjusting screw was tight,so it wasn't because it worked loose. I adjusted the screw, but it left no threads visible. The...

Wow didn't figure in the rocker ratio. Which is 1.5. Thanks for reminding me. But do you think the valves need to be re-lashed because of the low pressure when they were set? The pressure when they were set was about 12 lbs. Now it is 55 lbs. Anyone have an opinion?

When I first broke in the engine, my mechanic set the adj valves. It ran great and did not overheat. We discovered that the oil plug under the distributor was left out and caused low oil pressure. I have since installed the missing plug. My question is....Do the valves need to be reset, due to...

Fishy, Yes we got the plug installed and the engine now has 65lbs of oil pressure.:-D Thanks for all the help. Now, on to the brake problem. bwhitejr

it turns out the plug as outlined by fishy68 is missing, what size plug is this?????

Thanks for the great pictures! Is there a way using a small telescoping mirror to see both of the galley plugs and the backside of the engine through the distributor hole? Am I right in assuming the pipe plugs on the very back of the engine lineup with the galley plugs on the actual oil...

The machinist put the motor together. We received a short block with oil pan and timing cover on. We went to our mechanic's shop to initially fire the motor. And it has had low oil pressure since day 1. I have talked to the machinist and he said if I take the motor out and bring it to him he...

Looking back on the initial start-up of this engine, we had some trouble getting oil pressure. We put a priming shaft with a 1/2 HP drill motor in the distibutor hole and ran it wide open and got no oil pressure. We then started cranking the engine and running the drill motor we got oil up...

A picture would be great! Thanks, bwhitejr

Well, it looks like the only way to be sure, is to start taking the engine apart. What can be checked that wouldn't involve pulling the whole engine out of the car. Like remove oil pan, pick-up and oil pump. Or remove water pump and timing cover to see if the galley plugs are in there on...

I don't know if it matters but my heads are Edelbrock Performer RPMs and I can't see the lifters. BTW there was plenty of oil flow up top. We revved her up an had oil splattered all over the windshield. Notice the mechanical rocker assemblies.

The oil we used is Castrol GTX 20-50W. I need to look up all the places where there could be internal leaks. How can I tell if I really have a HV oil pump once I get the pan off? I noticed the 90 deg oil filter adapter has a plug in the end on the suction side. Could I put a gauge on...

Thanks for all the responses. My son checked to see if the one at 7" from the distributor shaft was in place and it was. If it turns out that the plugs we can get to are all in place. What would be the next most likely cause for relatively low oil pressure? Worn lifter bores? Is there...

Spent the weekend working on the 360 and collected some numbers. First of all replaced the 90 deg adapter with the stock setup and a PH43 filter. Installed a mechanical gauge and confirmed it reads the same as the electrical gauge. Here are the numbers: Inital start up: 12 lbs Idle...

I stopped by at lunch to my mechanic he said the problem could be that with the HV pump and a stock oil pan, all the oil gets pumped to the top of the engine. So it will start up with good oil pressure but soon drop down to very low, because there is no oil in the pan. He suggested a deep oil...

Where would this galley plug be? Is it something I can get to without taking the engine apart? bwhitejr

It is a freshly rebuilt '78 block 1 hr running total. When it starts it has 35-40 lbs of oil pressure. When it warms up at idle it has 5-10lbs (hard to be exact 0-100 psi scale). When revved it gets ups to 25-30lbs when warm. I am going to use a machanical gauge and check it this weekend...

I have a 360 with the 90 deg angle adapter installed. And was wondering if I have the correct oil filter installed. I am experiencing low oil pressure and wonder if it could be caused by the wrong oil filter. It currently has a Wix 51515. Also is there a way to determine if you have...

Have you checked for vacuum leaks? There is a fitting in the rear of the carb and the front too. Should be capped off. Make sure both rods are free to move. bwhitejr

The preoload is 3/4 tighter than zero lash. The engine runs great, idles great after the lifters get pumped up. It just takes a couple of minutes. Edelbrock requires you run adjustable rocker arms with anything above stock lift, for the heads I am using. bwhitejr

When I first start my 360 that has Adjustable Rocker Arms and Hydraulic Lifters. It runs rough and there is a lot of valve train noise. And it takes a couple of minutes for the the thing to smooth out. I guess it takes a while for the lifters to pump up and overcome the valve springs. Is...

I was connected to the driver side (alleged full vacuum) port. When I checked it, it appeared to be a direct connection to the middle, bottom of the carb. bwhitejr

I have a 360 with a Edelbrock Performer RPM manifold and Carter 625 AFB carburetor. I don't have a vacuum signal on the manifold port on the carburetor until I revv it a bit. And then I get 15" at 2500. I checked that the port is not clogged. The manifold is a dual plan and the cam has 60...

Does anyone know what the torque spec is on the 90 deg oil filter adapter bolt. The one that goes into the block? I have heard these things are prone to leaks, is that true? TIA bwhitejr

I know I should have checked the clearance between the valves and the pistons to make sure, but I didn't. So do I have any reason to worry using The Eddy Performer RPM heads, stock rods, Speed-Pro H116CP30 hypereutectic pistons (5cc valve notches) and normal head milling (for trueing). The...
