Oh I was also going to ask if any of you guys have noticed more under hood noise with lt's. There is less between the combustion chamber and the outside with lt's so I was just thinking it's normal. I need to check my bolts and make sure theyr still tight too though. And i think i may have a tiny leak at the ory. Though i will say, pacesetter lt's and 3" ory sounds insane through the 1993 style catback, i nkw im losing at least 10rwhp, but damn, it seriously freaks people out. I had a girl actually grab my arm and scream, then she asked me if it was supposed to be like that as i was trying to breath from laughter.

What I mean is that it's not something you can visually look at the engine while it's sitting there in the engine bay and go 'yup, it spun a bearing.'
thought a spun bearings would cause exterior impact, didn't know about that.

but it is strange because at first the headers got installed with good clearance. now at second time after the spun bearings there was very tight clearance, something changed!?confused.

Yeah the spun bearings just means the crank is grinding against a bad bearing and will mess up the crank journals and the bearing but it doesn't do anything to the placement or exterior of the engine that I know of.

And yeah, it's definitely strange but maybe it's just the poly mounts that everyone is saying.

so yeah, now that is logical it could be damaged engine mounts that made that tight clearance.

there not damaged mounts. if you look at the stock rubber on the motormounts they are pushed to one side over time. the poly will vibrate and move to the lower part of the housing causing the clearace to get closer. but the mounts once get to the settling point wont move anymore. its just how it is.
