Re: Bronze cam bearings

I'm dealing with a old Ford 312 Y block that Ford bored the cam tunnel crocked. I'm in Virginia. There is a gentleman in Texas that bored the cam tunnel to get it straight then custom makes bronze cam bearings for each hole. I'm trying to avoid having to ship the block to Texas. My research is telli...

Bronze cam bearings

If you were to make a set of cam bearings out of bronze with an outer diameter of 2.060 how much of a press fit would you give them.. and would you use loctite when installing?

Re: More 312 Ford Y block problems

I have thought about having the tunnel line bored. But where I'm located, finding someone that's done it before to feel comfortable with doing it is the problem. Fortunately the owner of the engine understands the issue and is in no hurry.

Re: More 312 Ford Y block problems

I've had to scrape bearings before. Especially on 350 Chevy's from the 70s. But on this engine the front two and the rear two aren't aligned with each other. That's going to be a lot of scraping. My concern is bearing clearance.

More 312 Ford Y block problems

Is it normal to see these engines with the housing bored for the cam bearings out of spec. My center bore is .0025 under the small spec and bored 4 and 5 are .001 under which would make the cam to tight. I also think they are not in align with each other. The front two seem to be on a different plan...

Re: Help with 312 old y block Thunderbird engine.

Head is off. No clogged galley. Fresh rebuild with starting to break cam in only. Oil comes out of hole very slowly after running pump with drill a minute or so. Took engine apart this afternoon and it doesn't have the grooved cam bearing on no. 3 journal. Will that make that much of a difference. F...

Help with 312 old y block Thunderbird engine.

This is a fresh rebuild. 60lbs of oil pressure. But almost no oil to the top of the engine. With head off and running oil pump with drill oil barely runs out of hole in top of block. Online search tells me this is a common problem with this engine. There used to be oil line kits to bypass oil pumpin...

Re: Ford dealership

I tried that on a couple websites that claim it will do that with the VIN but I got nothing. I'll try just googling the VIN .

Ford dealership

Anyone here work at a Ford dealership? I'm trying to find out if a vehicle recently bought has a specific option if given the VIN number. It's a few years old.

Re: 2.5 V6 Freelander

One more thing. I'm wondering if this is the way land Rover designed it to keep the pistons away from the valves while doing the timing belts? Because no piston is at the top of the cylinder.

2.5 V6 Freelander

I have a 2.5 V6 freelander engine that the customer tried to assemble at home. That didn't go well. He took it apart initially so I don't know how anything was when it was assembled. My question is about the timing belts. Everything I can find says there is an alignment pin that goes into the back o...

Re: Sunnen rod heater problem.

So that won't overheat the coils and damage them? Like I said, its been that way for 20 years and have not had a problem yet. If I remember correctly I never used to hear or see them do anything anyway. I imagine if you had one of the timers fail and left it on for an extended period of time that i...

Re: Sunnen rod heater problem.

z, I bypassed both of the discs on mine over 20 years ago and have had absolutely no problems. One of them would open intermittently and the other one had never opened so I just did away with both of them. It doesnt get used as much now days but still a couple of times a week. So that won't overhea...
