Yes, around .006/.010 is normal, check the rod side clearance specs to be sure as I don't have the specs here in front of me.
this is a pic I found online and then used paint on not my engine......... The motor in my 4runner which has 9,000 miles on it developed a loud knock a month ago so I parked it. Just got the motor out and I'm trying to figure out what's wrong
looks like you swallowed something. now that i think about it, i started to get a knock after i had a washer go into #3 mine looked pretty much the same, but then i drove it for 6mo did you notice a real sudden knocking?
High lift is more apt to cause problems on the spring side not in the port area, heat fatigue, lots of wear in guide allowing valve to wobble, or misalignment between valve when seated and the guide itself could cause failure. Whatever the case, it sucks
Yup, thats all they had available back home on Guam at the time... And to add to the fire that was #4 intake on my "Isuzu" motor!
soooo....... why would you want your guides off center so far? or are you running them untill you can aford the machine work for the bigger valves and seats
ya number 4 intake valve seat dropped down.....not sure why..........the entire long block has less than 10,000 miles on it along with everything else from the tranny forward including alt, starter, injectors, etc. The only "rebuilt" parts are the crank and block. The motor has never seen higher than 5k rpm too. At least its' warrantied but I still have to fork over the dough to ship it back, all my fluids, etc. Plus the fact that it's my daily driver.
