3400 interchange with newer engine

[jpey00]

Sorry to bother you GA guys, but I didn't get any responses in the Venture section. Not too exciting I guess. I know one of you will be able to tell me. Thanks.

Hello,

I need some information. I need to know if a newer 3.4 liter engine can be installed in a 98 Venture? I know that the 3.4 was the same from 96-99, but it is difficult to find a low mileage used engine. Can I install a 01-05 3400 engine without too much problem. If need be, I donn't mind stripping it down to the long block. I am however concerned about the cam sensor. From 96-99 the cam sensor sync ring was a missing tooth design. 2000 went to a single tooth design and 2003 went to a 50/50 raised and lowered semi-circle design. If I use the sensor designed for the sync ring, willl it send the correct signal to the 98 ECM? Is there anything else that might give me problems? Please help. Thanks.

only 01-03 will fit of the newer ones

What is wrong with the original engine? On mini-vans, it's easier to repair the original than replace the engine entirely (unless of course you threw a rod or broke a crank)

I believe the cam broke, oil pump went bad or shaft broke. Lots of noise and the oil light stays on.
