Re: 4age running rough, I'm stumped, pls help
To verify the timing mark on the crank pulley, stick a screw driver down number one plug hole and slowly turn the crank. when the piston reaches TDC, your notch on the crank pulley should be very close to your zero timing mark on the cam cover. My crank pulley's outer ring had moved about 25 degrees...

Re: t-vis butterflies
If you are going down the the T-VIS elimination road, remove the plate completely. Just make sure you pull the locator dowels stuck in the head before attaching. You will have to source shorter attaching bolts that are 8mm x 35mm lg. If you have the time, $, and tools, get a new themo gasket for the...

Re: Alternator on the exhaust side...

Re: 4A-GE 16v Rear Freeze Plug Info
Since you have gone this far, even if you do not see any coolant, I would clean around the freeze plug and then use 2 part epoxy to add a safety factor for a good seal. It might only weep coolant when hot. Dave W

Re: 4A-GE 16v Rear Freeze Plug Info
Before you jump into replacing a freeze plug [a real pain] Also check the steel coolant tubes with a mirror and a lite. I though I had a leaking freeze plug, when in fact it was a small pin hole rusted thru the coolant tube. Much easier to fit then a plug. Dave W

I've always had good luck when installing the cam seals, if I remove the front cam bearing cap , then side the seal on the shaft. That way you can verify that the seal is straight to both the shaft and head plus you can tell that the spring and lip are OK, before you re-install and troque down the c...

A quick check if you have an air compressor, is to apply air pressure to the cylinder(s) and listen to the intake, exhaust and crankcase for leaking air. Should help narrow down the problem. Dave W

Re: Gts driveshaft slip yoke opinions
You are asking a lot from the tail shaft seal with that rough of a surface to seal against. Even if it would seal it, the seal probably would not last very long running on that surface. If you are getting a custom length drive shaft made, the drive shaft company should be able to get a new yoke in l...

Re: Replacement Washers on Headers
Depending on how rough the surface is on the exhaust manifold, you met get better results using either an aluminum or brass washer from the local hardware store [will probably have to open up the I.D.] Plus adding a little permatex should solve the problem. Dave W

Re: Brake booster delete
If you remove the booster you really need to change the brake pedal lever ratio. The stock pedal ratio is about 3.8 to 1 [boosted]. You need to relocate the master cylinder up slightly and drill a new hole for the push rod that will give you a lever ratio of 5 to 1. You will be much happier with the...

Re: backside of waterpump tube
You need the tube to circulate the coolant before the thermostat fully opens. There should be an O-ring on both ends of the tube. Replace the O-rings and then coat both ends with RTV just before installing the head. Dave W
