I recently bought a 1998 tj wrangler 2.5l automatic. The jeep ran but not right,so I pulled the head to find two valves had cracked. I decided to go ahead and rebuild the entire engine. However when I installed the flexplate back onto the engine it hits the block! Am I missing some spacer between the block and flexplate? I have a bigger type spacer but I believe it goes between the flexplate and torque converter, thanks for any help!
