2002 jeep grand cherokee 4.7 vin to pin reader download
Hopefully you checked out the valvesprings when you had the valve covers off. Most likely the engine light isn't related to the noise but it could be. There are no codes stored now then so the engine light shouldn't be on at this time.

Please only rate my performance when you are happy with my help. A Durango or Dakota engine would have to come from a 2002 or older vehicle (not 2002.5, this is when the NGC switch was made), a Ram 4.7 would have to be from a 2002 truck. It would be safest to use a Jeep engine if at all possible. If you needed to you could use a regular output 4.7 from an earlier Dakota, Durango or Ram, although there are some engine mounting differences in Durango and Dakota. The PCM software is different between the HO and regular engines, you may be able to get by with your PCM or you may need to just pick up the one from the donor vehicle along with the engine.Īs far as other vehicles you wouldn't be able to use an HO 4.7 from any other. You'd notice a slight decrease in power if you installed a regular 4.7, but a 2002 HO engine may be tougher to find used. The internal differences between the regular and HO engine are pistons (compression ratio) and cam profiles. The regular output 4.7 though shows to fit 2001-2004 Grand Cherokee. The J VIN designation means that you have a high output (HO) engine rather than the standard 4.7, the 2002 HO engine doesn't show to fit any other years besides 2002. Later engines used an NGC PCM with a 32 tooth tone wheel. This uses a 16 tooth crank sensor tone wheel on the crank. The WJ body Grand Cherokee from 1999-2004 used the JTEC type powertrain control module (PCM).

Asking before buying is very wise! I've seen countless people install the wrong 4.7 and it won't run if the wrong engine is installed.
