hi all. today i changed my camshaft to a crower stage 1. all was ok car started up ran fine for a while but wen i put the foot down i heard a knock and the car stopped and wouldent start. on closer inspection it turns out that the stud on the gear(sprocket) that slots into the grove in the camshaft broke off so the gear was spining but not the camshaft. so of corse i gota get a new sprocket but how can i match up timing again since its now f**ked up! any help would be great!

once u get the new cam gear on put it at TDC and the crank pulley at TDC of #1 piston. u should be fine then. did u lash your valves for the new cam?

i would check to make sure you still have any valves left. what you are saying is pretty much the same thing as snapping a timing belt.

robbys89

ok cool thanks! i didnt lash the valves no. is it a must when upgrading to a stage 1? + if it is what shud i set them 2? this is the deepest iv gone into my engine before so bare with me im kinda behind! lol

good point!!

NVturbo

wow...I have never seen that before. Were you referring to the woodruff key?

robbys89

no the valves are fine and the timing belt! what happend was the sprocket on the camshaft pritty much rotated around the shaft instead of with it if you get me

94civiccupew/b7

u lash your valves anytime u change cams dude!! you should pull your head and check your valves they could be f**ked!

robbys89

if thats what it is called then yes! i dont know how it happend myself! i ether over torqued it or not enuf?

Nichelson_Performance

yea i understand, but if the sprocket was rotating and the camshaft wasn't that usually means that a piston will come up and smack the valve usually bending the valve and shutting the engine off and will most likely not start again

its just a thought

robbys89

okay will do thanks man!

robbys89

damn good point. the engine stopped strate away with no nasty sounds but i did try to start it again so couldof done more damage doing that?

Nichelson_Performance

probably to the valve/s it smashed. its a good idea to probably start looking for a new head

robbys89

yeah true. well first of all i will check them and see what ther like. if they are gone well least i got a 93 del sol with a b16a engine so i mite drop that in. shouldent be to hard since their all obd1 connections. my car is a 94 ex d16a by the way! shud of said that earlyier! lol
