Time for the compression check.

Very good data and detailed info forwarded to the owner.






















For some reason, this NSX is using PFR6G-11 instead of PFR6L-11 despite being full OBD2 spec.

It was like this from the previous owner.

I'm quite sure it left the factory with 6L-11 but don't know when they were replaced.

The plug centre terminal section looked bit darker than other NSX considering the mileage covered for getting to my place.

There was also not corona arching but clearly rust at the rear bank spark plugs.



















I'm going to replace all six to 6L-11 spec this time.


















Bit more extra rust compared to other 3pin style IG coil at the rear bank but nothing serious so going to apply silicone grease and re-use all of them.
