Do the exhaust headers need to be removed, or can the replacement be effected from the underside.

 

pretty sure i had to remove the headers. Not a lot of room in there/ really tight job...

 

This is how my project started. Cracked oil cooler housing replacement, then eventually the whole car...
I pulled my engine. I also knew the clutch was overdue. Hardest part will be alignment going back in, very tricky business. A good winter project if you have the time and a heated garage.

 

I have external oil cooler and was able to do it from
underneath without removing exhaust headers do have to remove heat shield.

 

I just did my gasket replacement on the oil cooler, without removing my exhaust headers. But, as pnbell says, it's a REALLY tight job. You might want to borrow an extra pair of hands.

 

plus 1 Correct no need to remove the ex header
