    Help! Timing Problem 327/365 HP Engineose

    Correct, 5 marks advanced would b 10* BTDC . I would turn the engine over by hand with a socket that fit your crank bolt and a large 1/2" ratchet or breaker bar, pulling the plugs will make it easier to turn but it can be done slowly and carefully with them in. You could also "tap" the...

    Help! Timing Problem 327/365 HP Engineose

    The engine timing marker looks good, it's on your timing cover, not your balancer/lower pulley. "A" is for advance, each hash is 2* of initial timing, 0 is TDC. Find the slash in your lower pulley/balancer and mark it with paint. Run the engine at idle speed with the vacuum advance (if equipped)...

    Exhaust for 77

    The Feds really do frown on this, no matter the state laws.

    Help! Timing Problem 327/365 HP Engineose

    Find 0 TDC on your harmonic balancer and put some white or yellow paint on it, mark your set timing (10* BTDC) in another bright color. Set your dwell (if points equipped) to 28-30 and then set your timing with the timing light clipped to #1 cylinder (left front). Always set dwell before timing...

    Inconsistent spark...

    If it was a bad ground at your ignition coil then the coil is most likely carbon tracked and needs to be replaced.

    Does power steering on a C2 increase engine temperature

    It would not cause a coolant overheating issue if it works properly. Yes, it is a parasitic drag on the engine, but not much.

    New owner, wierd charging issue.

    It sounds like a bad battery. Always the first place to start is to have a fully charged battery load tested with a real carbon pile load tester, even with brand new batteries. You need to prove that the battery is good before any diagnosis.

    Where to look for values?

    Maybe not, hard to tell. I would call the person who did the appraisal and get their opinion. Vehicle condition in 12 years could matter.

    1992 - Died after coolant flush, now won’t restart

    If it's an opti spark system, coolant could have gotten onto the distributer behind the water pump. Just a guess, I'm not real up to date on C4.

    Help! Mixing front/rear tires on 2014 Z51

    Any manufacturer will tell you to stay with 4 same type tires for safety, it's not a ploy or a joke, it's real. That being said, I see mixing and matching done all the time. It's your call and decision.

    Where to look for values?

    On something that old it is best to pay for a professional appraisal, it will come with documentation and a printout. I had it done on a 68 Camaro that I sold. Not cheap, but worth it.

    C4 Spark Plug Confusion

    Glad to hear you got it, good job.

    78 stalls unless revved and then seems to need to overcome high compression (or something) to restart

    That denotes possible improper firing time from either the cam or ignition. First things first, load test your battery with a carbon pile tester, you need to know it' good. If it is good, check carefully your cap and rotor and ignition coil for carbon tracks, any seen replace. Make sure the...

    2001 Z06 and Minor Issue (so far)

    How about finding the owners manual for that vehicle? Might tell you in there. I personally dislike auto lock and have it disabled on mine.

    C4 Spark Plug Confusion

    If this happened right after changing the plugs, you might have the wrong temp sensor location for the gauge. Double check for any sensors or wiring on the cylinder heads (between/near the spark plugs) for damage.

    C4 Spark Plug Confusion

    Disconnect the sender wire, and with the key on ground the wire with a jumper and see where your gauge reads. Note both disconnected (open circuit) and grounded (circuit to ground) gauge readings with the key on (ignition, not accessories).

    C4 Spark Plug Confusion

    Correct, you may have a reservoir and not a surge tank system. Does your temp gauge read correctly? If not find where your temp gauge sensor is located (usually on a cylinder head, but not always) and check the wiring and sensor for damage.

    1977 corvette -Tires

    Replace the tires, they are way too old. Anything over 8-10 years needs to not be driven on. Replace the battery, test it first if you want to but a 1994 battery will have o reserve capacity.

    C4 Spark Plug Confusion

    There should be a sensor in the coolant surge tank to tell you when coolant level is low, does yours have one?
