  1. p0325 p0171

    I finally got my truck running, i replaced the head and the fuel pump at the same time. Getting 2 codes p0325 Knock Sensor Bank 1 p0171 Bank 1 system too lean The truck sat with a half tank of gas for a full year with no stabilizer, could it be that this gas has degraded so bad and is causing...
  2. Cam Question!!

    I ordered a reman head from a company and when it got here, I'm pretty sure the cams are mixed up and on the wrong sides. I'm pretty sure the intake cam is the one that has the little nub on the end, but they have it on the exhaust side. Does this mean that they machined everything to spec...
  3. 1s7g vs 3s4g Head Swap?

    Well i ordered a reman 1s7g head and i got a 3s4g head instead. It looks similar at 1st glance but its quite different. It has extra oil ports and the cams protrude quite far. I edited this because i already got my answer. Im returning it.
  4. Metal gasket sealer?

    Replacing head. The actual head gasket, egr gasket, and coolant pipe gasket are all thin metal gaskets. I bought that copper spray-a-gasket stuff, is this all I'll need to properly seal these surfaces?

  6. Does this head gasket look bad enough for no compression in Cylinder 4?

    2003 2.3 180k Lost compression in cylinder 4 and was low on coolant. I pulled the head and checked for warpage with a precision straight edge. Everything seems to be straight and valves appear to be seated...at least I think, I don't really know how to check the valves beyond visual inspection...
  7. p0304 & p0316

    Crank Position sensor faulty and cylinder 4 misfiring. Both of these codes tripped at the same time. I checked for spark and it seems weak on 3 cylinders. Cylinder 1 is the only one with really bright spark. Anyone run into this problem? I guess im gonna try swapping out the coil pack first.
