Hello all,
Could some knowledgeable gurus please enlighten me about the valve clearances on the 4D68 ext R2SB engine?
I have two possibilities but not sure which is right:

0.25mm I
0.35mm E
or
0.15 for both

Grateful thanks
Martin

 

So I asked around, (not ever had to ask a question about a 4D68 before), but the guy I talked to said that they should both (inlet & Exhaust) shouldbe set at .25mm hot

 

Ahh, thanks! I think it's a good compromise. Thank you for going to the trouble. It's much appreciated.
Martin

 

no problem
