yes i know they are really core plugs so lets not go there.i am trying to put the cam plug in and it just wont go.i bought two sets of f.p.just incase i messed one up.this isnt the first time i have put them in and i have never hade a problem before.where i have the engine its only 40deg.could this be my problem?i can heat my office up to any temp i need.just didnt feel like wasting the electric.
im not sure.i usually use steel ones but i bought the br*** ones this time.i tryed to get one of them to go in the side of the block and it wasnt happening.the cam one is steel though.
I have had a problem with metric "soft plugs" (just thought I would throw a different name out there for ya) in place of SAE. That may not be your problem. 40 degrees should be more than warm enough for you to do what you have to do. You could try freezing the plugs that may shrink them enough to be a good press fit. I have also smeared gasket shellac on them before it works as a lubricant until it dries.
ok i checked the block size and plug sizes.cam plug is 2.141 on the starting side and 2.166 on the outer crush side,but the block is only 2.095.side plugs are 1.525 and the engine is 1.50.i did find a cam plug online that is 2.109.what is the press fit numbers for these sizes?the last thing i want to do is have them blow out or leak!!!!i have never had a problem before,but im sure all of the stuff not is comming from china.the plugs are elgin
What you are getting is metric plugs. I think that Boman makes plugs if you are buying local, they would still be made in the US, or call your favorite catalog speed shop and tell them that what you need is quality soft plucg made to the correct size. A couple of thousandths oversize should stay in but you'll never get on in that is a couple of hundredths. Perhaps if you freeze them like I suggested then take a propane torch to heat the area around the hole. I'll PM you a suggestion for a catalog store to get SAE sized plugs. At least its a place that I have always had luck with.
Try and find a engine supply there or stop by a machine shop, I order everything in bulk from Pioneer you can get any nominal or metric size needed. All my key ways plugs spring shims and locks pipe plugs cam plugs and pc seals all come from bulk Pioneer products. Alot of your carded supplies are just Pioneer products re packaged for resale.
ok so what is the right size{press fit}for a 2.095 cam plug?the guy i bough them from said 2.141 is right.
I checked my Pioneer parts catalogue and they say the cam plug is 2 7/32 (2.21875) which does not seem to match up with the dimensions you came up with. At least .003 interference fit will keep the plug in place but if you get much over .007 the plug will end up losing its shape, not be round anymore and never stay in place. I just measured a Pioneer plug (P/N PS154) and the OD is 2.023
so what should i do?i never had to measure a "block plug"before?am i missing something?it always seems like the simple stupid stuff kills me!!!!
As has been said, try a different brand. I'm a retired machinest, and .001 interference per 1 inch diameter is about right. If you have .046" interference, you will distort that plug all to hell by the time you beat it in. Just for reference 1/16 of an inch is .0625"
If you can get a 2.109 plug and the cam bore is 2 .095 there is only .014 difference. That would be the correct size. That 2.127 is 54 milimeter.
it the factory orig.amc blue.its more of a teal with metal flake.yeah i think its the coolest engine paint color!!!
