First time, long time. I love the forum and have been getting some great advice on my Taco from just reading all the posts. Now, a recent situation with my truck has me at a crossroads and I was hoping for some help/input from all you good folks out there. Here goes;
CEL came on a few weeks back, so took it to Auto Zone and of course the notorious 'misfire' code showed up (p0302 to be exact). It had been a while since I changed the plugs, so I figured that would do the trick. No rough idling or any other discernible issues with the engine. Even now the truck runs fine.
About a week later, CEL comes back on, same code. Came onto the forums seeking advice and it sounded like switching the coils around might work. Nope. Still p0302.
Took it into the shop and turns out the #2 cylinder has low compression (70psi dry, 90psi wet). Had them check the ignitors and fuel injector, both looked fine. Both places I took it to recommended new valves and head repair. Around $1700 was the estimate. Both places said this might fix the problem, but it sounds like this isn't an uncommon problem with these engines and could easily happen to another cylinder(s).
My question is, do I pay the $1700 for the new valves and head? Or should I be looking at a reman/used engine for my truck? Looking at about $5000 total for an engine swap. Has anybody been through this process before? Any recommendations or tips? Can I sell my old engine to a junkyard or somewhere else to help offset the cost of dropping another one in? I love my Taco and other than this problem, the truck is in fantastic shape. I would like to keep it and run it for another 300K+
Specs: '99 SR5 manual, 2.7L, 4 cylinder, 164K miles
Thanks in advance for any help!
