Not really.. I have been involved with quite a few Q&A from people that have moded their cars, and then had issues!! Heads.. Cams... Headers.. even changing pulleys.. !! And they claim there were no 'noticeable' issues befor the mod. There are a few shops NOW, that will suggest the check out befor any mods, and some dont.
And it seemed to me that a lot of people dont realize that these issues are beginning to appear more often as the car gets a bit older and more miles, and has been driven hard.
Just a heads up for future 'fun'..... and we all need to know!! yes??
Would it be good to get compression tests and a leak down test on a car I've owned since new with 80,090 miles in 8 years? Been maintained religiously.
I installed an intake at 17,000 an oil cooler at 20,000, a pulley at 28,000 miles, and an RMW tune at 58,000. Besides some suspension, brake stuff, and replacement parts, the car is otherwise mechanically untouched.
No signs of anything wrong except occasional valve train chatter when cold. Oil level is stable since last change for the first time in car's life. Coolant can boil over onto the headers sometime, but it has been flushed professionally and a new thermostat installed.
IF you are thinking of getting into the engine components.. Head.. Camshaft.. or a major change to the exhaust, YES I would suggest at the min having the shop do a compression test!! There are a lot of shops that have learned over the years, and they will probably ask for a "pre-Mod" test anyway!! It really is for the customers sake!!
That is not followed very often.
