How many degrees of stretch are you getting? This can be measured by alligning the engine at TDC and then checking the camshaft mark at the stantion, if you arent aware of this already.

Meanwhile the price of fuel remains artificially low so the imbecile Bush has better chance of getting re-elected. In my industry, transportation and trucking, we are getting clobbered with $2.19 prices for diesel. Yet most people believe prices will reach $2.60 by January and then stabilized near $2.25 at the lowest.

Another way to accomodate stretch and chain slap is to see about an offset woodruff key for those European camshafts you installed. And they made a couple of different chain tensioners too: hydraulic and mechanical. Some might have a longer throw than others.

Gone are the days of cheap gasoline. And with the idiot GWB driving national debt through the roof and cutting taxes for the rich, it's gonna be cold day in hell before fuel and road use taxes go down.

And those alloy chain rails can be resurfaced with fresh rubbers. Possibly brake shoe resurfacing company can tell you where this can be done.
