Hey guys, i have a question about using grease with plastigauge.

In the instructions it says to use a smear of grease on the crankshaft journal, so i did and the clearences are where i wanted them.

But i then tryed it with no grease, as someone told me i'm suppose to do it dry as it will effect the reading and the clearences where quite loose.

Which do i go for ? I have used mainly black bearings so even if i had to do it dry the only next size up would be blue and that still would'nt be enouth. Also i went buy the letters on the engine and numbers on the crank.

The clearences were .0015 with grease & .002 without ? ?

Cheers

 

Follow the instructions and use the grease. Without lube the gage won't be free to spread out as much, thus you'll get a thinner line and a erroneous wider clearance. The gages will only read correctly if you follow the instructions.

 

well put!

 

i just did mine 'dry' and they came up at 0.002 across the crank...

that's why i came on HT to search, and found your thread

my plastigauge packet didn't come with instructions,

so do you guys mean that i need to put the assembly lube on the journals before i put the plastigauge on them?

this is the first i have heard that?

 

ive seen a few videos youtube.

 

i am more interested in seeing the instructions the guys above are referring to?

these are the only instructions i could find:
