1998 Chevy Venture camshaft
Any help would be so much appreciated. The camshaft on our 1998 Chevy venture broke. It has a 3.4L V6. So we call on a price for a new one to replace it. It had to be ordered. Now we have run into a problem. The camshaft that originally came out of the vehicle was hallow. The new one is solid. Also on the back end of the old one is a small round 1/4 inch lip. The new one does not have this, it is flat. The parts dealer says that the one we bought is the correct one. He double checked the parts numbers. So now we are not sure what to do. Has anyone ever heard of a hallow camshaft. Do we try to use the new camshaft.

i'd take the new one and the old one into the parts dealer and show him that its not the same. if you ordered and OEM cam then it should be the same as the old one. try going to a chevy dealer in the parts department and show him what the parts store gave you. they should be able to help ya out.

and if you bought the cam at autozone... its probably the wrong one. their computers are so screwed up with wrong part numbers and mis-matched info its not funny. they dicked me over 3 times, on simple stuff that i dont even go back anymore.

if the journals on the cam arent identical to the old one, i wouldnt even waste my time trying to use it. your likely to roast the bearings. well, hope i've helped. good luck. :thumbup:

Camshaft problems with the 3.1 and 3.4 are fairly common. I would want to be very careful and research this completely before you install that cam. Call some of your larger machine shops and ask them their experience with them.

Be certain you haven't spun a cam bearing in the block. This is a common problem.
