Open Question

I need to reset the timing on my 1987 corvette convertible L98 engine. The manual just says to set it to the specs on the emissions plate but the problem is that the settings are faded off. Do you know what the settings should be?

SOURCE: 87 samurai bolt torque specs for engine

The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.

The factory service manual is the only way to go.

Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)

Intake & exhuast manifolds- 13.5 - 20 lbs

Flywheel - 41.5 - 47 lbs

Clutch cover - 13.5 - 20 lbs

SOURCE: i need the torque specs for a ford 300 inline 6

Tighten all bolts to 10 Lbs, then 20 Lbs, then 35 Lbs.
That should be fine for the 6 cylinder flywheel.

SOURCE: I have problem with my Corvette C4 L98. Engine

I would check out a) all vacuum pipes from your intake manifold for cracks etc. b) fuel pressure regulator (FPR) valve and your ignition coil. The function of these last two is not overseen by the engine ECU and if they are not behaving then you are the best diagnostic. Any small air leak into a vacuum pipe will compromise the intake manifold pressure management and the car will run roughy. The FPR is a small metal circular device and sits on the fuel rail; it has a vacuum pipe attached to it. Sometimes if the FPR is failing there smell of fuel from the vacuum arm when disconnecting the small diameter vacuum pipe. If the FPR leaks it makes the engine run richer than it should and the consequence is the ECU then alters the engine management to cope. This can lead to non-fire events and occasionally miss-fire as the engine goes from rich to lean and back again: basically mirroring the same events as with the cracked vacuum piping (above). Finally check that you are getting a good consistent spark on all plugs. Now check the resistance of each spark plug lead, they should all have high resistance but anything that looks extreme, compared to the rest, should be replaced. Remove the coil and give it a really good inspection, check for any cracks or obvious signs of shorts. Sometimes an intermittent short in the low tension coil side is really hard to detect but it will give rise to non-fire events. I keep stressing 'non-fire events' (or failure to fire) as miss-fire (out of time firing)) is often detected by the knock sensor etc.

The clutch disk and pressure plate should be balanced and can be mounted in any position that the mounting holes line up. If there is a hole for an alignment dowl, then it is recommended to do so. otherwise it doesnt matter.

The internal balancing is taken care of by the flywheel only.
