The shop messed up. But bottom line is the person assembling the engine. You have to check everything TWICE. Put it together and call it a DAY. Not trying to be critical. but this issue should have been caught by the builder. You can not rush when assembling an engine. To much at stake. That is why i do it in a desperate room and lock the door and hang the sign not to disturb. 2 people can not build an engine. And once again always replace everything removed from the engine and store the parts in a basket or paint bucket ETC. Things happen i know but that missing plug should have been caught either by you your son or the builder. Good luck and carry on.

Tom,
With the plug missing in the location it was missing what are the chances that the main and rod bearings were hurt? My guess is that they were not as the leak was past them but I am not sure of that. I am not thinking this would have been a question of volume but would have there been enough pressure to maintain the thin film of oil necessary between the bearing surfaces and the crank surfaces?

Jay,
My take on the machine work is that if you pay someone to do a job they should do it. If the machinist was charged with installing all of the freeze plugs and oil galley plugs then he should have done so. I my line of work I cannot recheck all of the work that is to be done that I assign to my guys or what would be the reason to have them do the work? We pay good money to people everyday and expect them to do their job for the wage that is paid and this is no different. What should the compensation be? I am not sure but the one thing that any person has to give is time so I would at least expect some kind of written agreement to knock of some dollars on the next project he did for me. People make mistakes so that is not the issue, the issue is he was paid not to make mistakes.

@ Aerocoupe. That engine is fine and not hurt one bit. BUT one has to wonder what else may be wrong with the work performed. Over the course of many years i have seen some very bad machine shop work. As far as your question i have seen many a 2.3 with the CAM PLUG sitting in the back of the head laying there and wiping out a cam. But the bottom end is fine. It really does not take much oil pressure to lube the rotating assembly. Remember lets say the engine made 10PSI of pressure. That is PLENTY. Always double check stuff. Never trust anyones work. That will bite you in the TAIL. All is well but what happened here and pardon my bluntness. Was an engine slammed together to make a deadline and not checked and assembled properly. NEVER RUSH an Engine BUILD!!!

Jay just something to think about!!!! When Pontiac engines were popular and they still are i used to drill a tiny hole in one of those plugs to oil the TC with pressurized oil. It actually used to SQUIRT ON THE CHAIN and make the chain live longer. On SBC engines i drill a small hole in the TIMING gear thrush face for the same reason. But on the SBC where i drill the hole it intersects with the reliefs of the gear and intermittently squirts 4 times. Every time the RELIEFS lines up with the hole. The installed plug with the hole shows very poor workmenship on the machinist side. Clearly he used a punch to install that plug that was to small. Those gallies should have been TAPPED for pipe plugs or allen bolts and sealed properly. Sorry to say your machinist is a PUTS!!!

Just an example of checking things out thoroughly!!! Never trust ANYONE. Or any part!!!

There you go JAY pressurizing the engine on the stand. That is what i am talking about. If you would have dun it before this post would have been NULL and VOID. Always check an engine for proper lubrication on the stand. And if you hook up a gauge you can make Oil pressure static adjustments right on the spot.

At least you got it working. That was a pain.

I remember when I went to pick up the engine in my Thunderbird from the machine shop that shop had had filled the pan with oil, spun the oil pump, and made sure the engine made pressure and flowed ok before they would let me take it. They did that so I wouldn't run into what you did. My engine was assembled by the shop though. The engine was drained before I took it home. It would have been silly to leave it full of oil

also, my engne machine work was due by 12aug.
we got our engine block at 5pm 15 aug
we got our heads at 3pm 16 aug
my sone had to be to work at 4pm 17aug.

my original post stated that we explained my deadline to the machinest,,

but yes, it is our fault for not finding it.

i asked "what does good oil presure look like" when the oil archs across the rear two lifter bores and got no answer.

now i know what it looks like back there.

JAY i posted it is a stream not a rush of oil. I answered you question and it really does not matter. As a missing plug in the front of the engine GALLEY upsets the whole mess. As you posted above those rockers are oiling and it sure looks like you Pre loubed with the front cover OFF. This would have saved tuns of issues gaskets and time if dun in the beginning. I do understand that you do not assemble engines every day. So looking at oil flows takes a lot of experience and knowledge. With that you are good to go so ponder on. As far as the engine being delivered on time once again I NEVER SET A DEADLINE for delivering an engine. Once itis dun i call and i make sure it is checked out completely. This is one reason i personally do not do parts of an engine i do the whole thing. And before i do an engine for a customer i take HIS OR HER DIZZY. Upon completing the instillation i have the customer either bring me the car or i get it install the DIZZY and i start it. NOT THE CUSTOMER. This is of course debatable on the skill set of the customer. With that have a great day and BUTTON UP THAT MILL. Thanks

Jay as a FYI when you get the roller rockers set the rocker shouldn't be noisy. They will be a bit louder than the stock rockers in your Cougar but there should be no tapping or rattling. The roller rockers on my Thunderbird are torqued to 20 ft/lbs with a think shim under each rocker. It took ½ turn on each rocker bolt to reach that torque number. Using the stock pushrods that torque spec gave me a lifter preload of .030 inches on all of the lifters. The valvetrain is quiet. It’s a little louder than the stock one in my Mark VII but it has no tapping or clanking what so ever. With the cam I have (slight overlap and a bit of lope) it idles at 700 rpm hot in park and 650 rpm hot in drive and pulls 17” of vacuum. http://www.youtube.com/watch?v=4alJMV1cG2k

Also when setting the base idle on the engine use a tach/dwell meter. The stock tachs are off by about 200-300 rpm, at least my digital one in my Thunderbird is.

Jay i must be missing something. If you checked it on the stand why in the world would you install it in the car AND RUN IT IF IT WAS NOT OILING THE ROCKERS Just curious

Thunder jet how thick was the shim you used?? And i am just curious why you would shim a pedestal if FORD says PRE LOAD can be as high as .080. Shimming the stands changes the geometry did you check the contact area. Just a question!!
