RS4 RTR3 Problems

[Nitroz28]

I was Running my RS4 today and it started showing signs of a air leak . stalling and reving up and down at idle. then it lost all compersion and wont run at all. this is a 1 month old RS4 . So i took it home and looked at it. I noticed that when it was on its compersion stroke i could hear air escaping between the head and case.

so i went to take the head off to look at the piston and the 4 screws on the head were lose and i mean VERY LOSE. The only screws i forgot to check when i got it.

So, i took off the head cleaned it up every thing looked good. and put the head back on and tighted the screws good. so i test fired it up and it started up on first pull and hadd the most compersion i ever seen EVEN MORE BEFORE I BROKE IT IN !!!. But it runs good now very good.

BUT, my question if the head was loss throgh break-in and alot of TUNNING :devious: . abot 2 qaurts of fuel through it . Will there be ne thing that could have worn out faster b/c the head was not tight ? if soo i wanna call HPI they shouldnt send u a engnie with a head tighted by a 2 year old kid thats how losse they where one was starting to back out. ne advice will help ..:thumbup:

I would think even with a loose head during break in that as long as you let the engine temps rise and then cool properly that your engine should be fine. As long as no trash was able to get in there and the tempature did not get too hot, I would think nothing would be damaged.

i cleaned it up and nothing got in and i broke it in good forgot to put piston at bdc a coulpe times but other then that , ill see if it runs better now b/c i been tring yo tune in ever since i did the break in now i can finally tune it and see the speed with the much more compersion it will have now..:marshall:
