Pilot bearing knocked out my engine plug

[90zr1blknred]

Help I have a 90 zr1 I was replacing the pilot bearing on and I knocked out the engine plug behind it. Any tips on how deep to set my new plug since I don't have a reference now. And tips or tricks to set it right. Thanks everyone.

The following thread should help. Good luck and don’t worry, this stuff happens to all of us.

Thank you so much

By "I knocked out the engine plug behind it" do you mean
pushed the rear engine seal into the engine? Can that happen?
That would be no bueno.

[90zr1blknred]

Yes I popped the plug into the motor and need to install a new plug after I tear the entire clutch and flywheel out again. Ugh.

Yeah...pushing it through...is different than pulling it out. It happens sometimes. But, I don't recall what (perhaps it was Marc H) may have said about it. Is it a "biggie"?? IDK either.

I'll camp on this one....:happy1:

No big deal. It drops into the oil pan and you put in a new one. I’m told it will be ok if I set the new one correctly. More worried about not screwing that up and what the best depth is to put it back in since I have no reference as to where it was originally. Ugh

Would this be the miniture looking freeze plug pressed in the crank?

[90zr1blknred]

It’s defiantly a miniature freeze plug. It’s behind the pilot bearing. Holds 12 quarts of oil in. Most frustrating mistake I ever made. Put it all back together to find out I punched it in by accident.

Were you able to locate it?
If it is pushed into the crank, it may restrict or block oil pressure to passages for main or rod bearing. Going off memory, which it's been 10 + years I had it apart, but I don't think it is possible for it to make it to the pan if pushed in. I hope you found it, or I'm wrong, because it could be hard to get out of the crank. But worse if a bearing starves for oil.

The rear crankshaft cup plug seals the lube oil bore in rear main journal. There is another pressed in cup plug located forward of it to seal the other end of the bore.

The dislodged cup plug should be fished out first before installing a new plug. Be sure to thoroughly clean the rear cup plug sealing area with suitable solvent and install using Loctite 620 and J38837 rear cup plug installation tool according to FSM instructions.

Isn’t the crank on the front of the block? When I spoke to Haibeck he said it would just drop in the pan. Please let me know if that isn’t correct. I havnt went to put the new plug in yet but will be taking the Tranny out soon.

Sorry, can’t understand your question.

Do you have any thoughts on how to fish this out given that it was a tight seal engine plug that was pushed in. I fear it won’t come out but Haibecks thought was that it would just drop into the pan and wouldn’t be an issue. I appreciate the different thoughts here as I’m not certain what the effects could be if I can’t get it out.

Once you have removed the transmission, bellhousing, pressure plate, and pilot bearing you should have good access to fishing it out. Referring to the above FSM page you should be able to turn the plug sideways by maneuvering it to the exit area of the drilled oil passage coming from the rod journal. Then yank it out with a good pair of long nose vice grip pliers.

Update:
All torn apart and the cup plug was just sitting there loose. I cleaned it all up and punched in the new one with red sealer. Getting it put back together now. Can’t recall all the torque specs for pressure plate and bell housing does anyone know off hand.

Anyone know what the torque is from pressure plate to aluminum fidenza flywheel. It can?t be 100 N-m

Torque of pressure plate bolts to stock flywheel is only 30ft/lbs, with red loctite. Fidanza recommends OEM MFGs torque spec.
