It has been dripping Coolant for a long time and today i started taking it all apart to replace it. I recently measured chain and was shocked to see that after 8 months and 3000km the chain has stretched to over 1%. he was checking my cats. That's why you never reuse them. In most cases a 1/16, 1/32 or 1/64 note timing will work to create a slap effect. The oil seepage may be due to surface porosity in the aluminum material used to make the engine timing cover. 4 heard timing chain slap other than the noise the engine ran perfect and had no codes. Timing failures: We use all new OEM timing components in our rebuilds that include upgraded tensioners & guides to prevent chain slap & failure. i just replaced my t chain on mine casue it was clattering and slapping the block but the good thing was that a new timing set was only like 80 bucks at autozone and it came with tensioners, guide,and a chain but my old chain was stretched about an inch more than its supposed to be oh and when you replace you t chain replace your water pump too. They have an automatic chain tensioner on each cylinder, but they can be adjusted to get rid of extra noise.
