Im in the process of doing a Vitara and TT knockoff rod setup and I know some of you noggs are very familiar with Honda engines, so, I was hoping one of you would LMK if this D16Z6 crankshaft looks damaged. Its the main seal end, and the groove looks like it was machined from the manufacturer, but a want to be sure.
Thks

 

ur fine paco

 

if it wasnt leaking before i wouldnt worry...

 

the cam seals do the samething, ull be fine

 

EEExcellent!

 

It wasnt machined from honda, all cranks will look like that after years and years of spinning. it was the seal wearing away the metal, hard to believe, some crazy ----. mine looked the same way but now i'm getting a drop of oil out of my bell housing, damnit. I would just adjust the seal so it doesnt ride in that groove and you should be fine.

 

Good stuff, Thanks.

 

they also make somethign called a speed sleeve. it is a very thin sleeve machined to slide on the crank. you put it on there and it covers up the grove and gives you a nice serface for your seal. or you can make sure the seal doesnt ride on that groove, whichever you like

 

The reason that happens is that the seal is made of Viton which has a high silicon content. It acts like really really really fine sandpaper and after years thats what happens. Dont worry about the new seal running in that spot. It has actually polished that surface and will seal just fine. Be careful when you are putting in the new seal that you are not hitting it with so much force that you throw the garter spring off. Also be sure to put it on square. That is the most common root cause of failure with crank seals.

 

Thank you

Ok, Thank you
