I thought I remembered that when I bought my 1998 Quest GXE that it was listed on the window sticker as having a DOHC, 4-valve-per-cylinder,
3.0L V-6. It definitely has two cam shafts visible throught the oil filler. Mitchell refers to a DOHC version of the van in that year, but evidently no one else knows about it. It looks like the common SOHC engine has a timing belt, but the DOHC has a chain. The van now has 110k miles on it. What is the recommended life of the timing chain on these vehicles, and what is a good source for them (local auto parts stores only list parts for the SOHC)? Thanks for any assistance.- posted
