    Emissions Failure -- HC at idle

    Thanks for helping out Rick, I'll try to answer your questions. Complete test results: >>Idle Results<< Rpm = 870 HC = 806 ppm (fail, limit = 400 ppm) CO = .72% (pass, limit = 3%) CO+CO2 = 10.52% (not required to pass for this vehicle, but exceeded 6% limit) O2 = 6.77% >>Cruise...

    Emissions Failure -- HC at idle

    Thanks, I really appreciate the feedback. If I were running lean would I have seen evidence on the plugs I replaced? They were tan and looked fine. My thought on the EGR is that it is normally de-activated at idle so it shouldn't be a factor in my emissions failure. The timing is well...

    Emissions Failure -- HC at idle

    I've just failed the dreaded emissions test (twice) here in WA state. HC is too high at idle (800, limit is 400). HC passed at cruise (50, limit is 400). CO passed at both idle and cruise. Here's the details: - Between failures I replaced the air filter, spark plugs (NGK), and changed the...

    Timing Gear Whine

    The gears are non-OEM so no dampener ring on the cam gear. I think I will just live with the whine unless it gets worse...it sounds funny for a 2F though. I'll just pretend it's a supercharger.

    Timing Gear Whine

    I've just replaced the timing gears on my 2F, which were pretty worn and exhibited excessive backlash. The new gears meshed well when installed, so well that any backlash was indistiguishable. Upon restarting the engine, I'm getting a noticeable whirring or whining sound from the timinig gear...

    2F Engine Knock

    Just an update to bring some closure to this thread for future readers. I replaced both timing gears and had both the camshaft and lifters re-ground. Last night I fired it up and the knock is gone! Ultimately, I believe the knock was a result of excessive camshaft end-play and worn gears (too...

    Camshaft Replacement Questions

    Thanks for the input. My cam is on it's way to Delta Cam for their RV grind (.255 lift, 215 @ .050). I'm not too worried about reusing my existing cam bearings because they only polish the journals and don't cut any metal. From what they say, this is a drop-in modification that should not...

    Camshaft Replacement Questions

    Bump. Any thoughts or answers to my questions above would be greatly appreciated. I need to get this rig back on the road this week! Thanks.

    cam specs.

    JP2ME: Did you end up using this cam? If so, are you happy with it, and do you have any other engine mods that relate to the cam (intake, exhaust, re-worked heads)? I'm considering a re-ground cam from Delta for my stock 2F. Thanks for the info

    Camshaft Replacement Questions

    I've got the cam out of my 2F and the lobes and lifters are showing minor pitting. I'd like to replace the cam, but there is no way that I'm going to replace the cam bearings (motor is still in the rig, and there is no way it's coming out!). Has anyone had any luck replacing a cam without...

    2F Engine Knock

    No, I've read too many bad things about the OEM cam gear. Plus, the one that's in there is in pretty good shape.

    2F Engine Knock

    UPDATE: Camshaft Thrust Clearance After many months of enduring my engine knock, I finally tore into the front end this week. To my delight, I found that the cam thrust clearance is a whopping 0.032 inches (nearly 3 times the limit in the FSM). I am assuming that this is the source of my...

    2F Engine Knock

    I did not feel any excess play in the wrist pins when connecting rod bearing caps were off. My next free weekend I will take a look at the timing gears. That will give me a chance to inspect the cam, lifters, and pushrods while I'm at it. I am getting a crash course in 2F internals, good...

    2F Engine Knock

    Ok, so it's not the fuel pump because I swapped pumps w/ my roommate's FJ60 and the knock was still there. Also the noise is concentrated at the front of the motor, away from the distributor. It looks like Pin Head may be right all along w/ his cam theory. I'm thinking cam bearings...

    Fuel Pump Question

    Just to follow up, I swapped in my roommate's fuel pump this evening and my motor was still knocking. One curious note was that I realized the two fuel lines coming from the gas tank were installed incorrectly before I owned the vehicle. The fuel line w/ the fuel filter was hooked up to the...

    Fuel Pump Question

    Thanks for the replies. It sounds like my pump is fine. I may swap in one from my roommate's FJ60 this weekend just for fun, but now I'm doubting that the fuel pump is the source of my knocking. It's a little disappointing, I was hoping somebody would tell me that my fuel pump was totally...

    Fuel Pump Question

    I'm chasing down a knocking noise that seems to be coming from the area of the fuel pump. I pulled the pump this evening, and it passed all the functional tests in the FSM. However, the lever stroke seemed pretty short (1/4 inch) and it was somewhat difficult to move the lever by hand. I'd...

    2F Engine Knock

    Thanks for the additional suggestions. I'm going to take a closer look at the fuel pump and distributor because they are the easiest to access. Since the knock is coming from the front of the motor, the fuel pump is my number one suspect.

    backspacing

    I'm running 3.5" backspacing on Unique 15x8 (#27-5860) with 33x12.5 tires and 2.5" suspension lift. Sorry I don't have any pics, but the tires appear to extend a bit outside the front fenders and just flush with the rears. I'm happy with the stance, and I definitely wouldn't want it any...

    2F Engine Knock

    Ok, I'm stumped. I tore down the bottom end and found a few surpises. Rod bearings and journals were in good shape and oil clearance was within spec. Main bearings and journals were in good shape as well, although oil clearance was a little out of spec but did not exceed the "limit"...
