I just finished the test drive after adjusting my valve lash tonight...
I go on the tight side of spec for both intake and exhaust valves. I noticed a slight "whum whum whum" diesel after the adjustment, normal stuff when you go tight on spec though. The rattle under heavy load could be you hearing the exhaust due to a small leak at a seal or, if you have aftermarket single wall pipe you can hear the exhaust ever more slightly. My car does this a little bit due to a cruddy donut seal at the header and Cat.

Basically, as long as the noises don't get louder, you'll be fine.

Just wanted to say the car hasn't been hesitating anymore. Still has small power surge from time to time, but prolly an o2 sensor. if it gets bad I'll replace the o2 sensor, but for now the car is really running near flawlessly. The only thing still is the same things I've said forty times over: surging idle and sticking RPM when shifting etc. It actually has stalled several times lately. Originally the mechanic had quoted me $140 for used throttle body installed, now he is telling me it isn't available locally and the throttle body alone will be $140 (so $200 installed) Not sure if he is just saying this because he realized new ones are expensive and he could be charging me more. Might ask another mechanic on Monday. Would be nice to have the car purring without any quid pro quo. But I feel the valve adjustment really helped!

Don't pay to have a tb installed. Buy one online for like 10 bucks at most and DIY or come up here and I'll help.

haha! I like you for that. Yeah, man, next weekend! would be grand. The mechanic also offered tweaking the already tampered throttle body to see if we couldn't fix the problem that way -- but I don't think we'd be able to fix the surging idle. Btw, what do you want as compensation? You end up bringing your tools up?
