I have about an 1/8 inch gap between both points where the dowel pins go into the engine block. The top two bolts are in flush at the top and the pin closest to the front has the bolt tightened seemingly all the way but still has the gap. Haven’t engaged the tob yet, removed the tranny for exedy twin. Wondering if anyone has any ideas. Been sitting like this for a couple days.

 

Sounds like an assembly issue, not the dowel pin.

 

was it painted? sometimes paint makes it tough for the dowels to go in.

pull it back off... clean up the dowel holes...
try again.

dont force the tranny on by tightening bolts
this messes stuff up.

you should be able to get it to flush up just by hand

 

Are you sure the clutch was successfully stabbed?

 

Definitely wasn’t painted but the pins were pretty crusty so I’ll try and clean them up and hopefully it’ll go in.

 

define stabbing the clutch?

 

Getting the trans input shaft in the clutch disc(s). It you aren't quite right there, it will cause issues similar to this.

 

shaft is definitely in both discs. I’m thinking it could be hitting on the metal plate between the block and trans and or the pins are rusty
gonna attempt to put it in later today

 

If the pins are a little crusty, that would definitely be a place to start.

 

Update:
Took transmission and clutch back off to move the metal plate the better align with the dowel pin holes. Put everything back on and now the front pin will go in, just not the one closest the the transfer case.

 

Why are you having to "align" the block plate? It bolts to the block with 2-3 small bolts behind the flywheel. It'd it's bent up, just replace it.

 

lol yes I know, I replaced the plate already and had to realign the dowel pin holes because it was hanging low 1/16 of an inch

 

Something it's definitely not right here. Dowel pins and holes shouldn't need to be realigned nor hang any amount lower. Do you have someone that can take a look at it for you?

 

I tried, the mechanic that helped tuned my car said he would but ghosted me twice so rip. First pic is of the back pin.
second pic is the first pin thats in

 

So I put a second jack on the back of the tranny to lift it up, then worked in the bolts. Shes now all mated up👌🏼
Thanks for the input everyone!
