banzai510(hainz) Posted September 8, 2015 Report Share Posted September 8, 2015 It's easy to isolate. Its EZ to take the front cover off. Hard part is ripping the oil pan gasket front. But you cAN SPLICE ANOTHER IN IF IT TEARS 1 Quote Link to comment
KoHeartsGPA Posted September 8, 2015 Report Share Posted September 8, 2015 The pan gasket is new, should be ok and survive the job. Quote Link to comment
banzai510(hainz) Posted September 8, 2015 Report Share Posted September 8, 2015 Lower the pan and hope it dont tear 1 Quote Link to comment
Doctor510 Posted September 8, 2015 Report Share Posted September 8, 2015 The pan gasket is new, should be ok and survive the job. IF it has not been super glued to the bock and front cover 1 Quote Link to comment
datzenmike Posted September 9, 2015 Report Share Posted September 9, 2015 Take the valve cover off and you have a direct shot to the sound.... if it is the chain. You might even see what's causing it while it's running. If you have a spare valve cover cut the front off and install so the oil doesn't spray all over. Taking the chain cover off is too drastic right now and you won't see or hear it running. Quote Link to comment
Draker Posted September 9, 2015 Author Report Share Posted September 9, 2015 I did that already. While running.. everything looked fine. No obvious slop in the chain or guide. Warning oil will go everywhere. Quote Link to comment
Draker Posted September 9, 2015 Author Report Share Posted September 9, 2015 When I fix it, I will likely just pull the motor. Put it on the stand and fix it. It takes less than 2 hours. I have had this motor in and out many times already. One more time won't hurt. Quote Link to comment
Doctor510 Posted September 9, 2015 Report Share Posted September 9, 2015 Sounds like a loose or broken chain guide Be sure to send pics or let us know what you find 1 Quote Link to comment
datzenmike Posted September 9, 2015 Report Share Posted September 9, 2015 Sounds like any L series to me. 2 Quote Link to comment
banzai510(hainz) Posted September 9, 2015 Report Share Posted September 9, 2015 Sounds like any L series to me. That's what I first thought also.But I think I heard a grinding last time I had that my tensioner was out and cocked 45 deg upward thus wearing the bottom thin side of the shoe which was going to metal. tother time the tight side guide I ran a longer screw in the stat housing thus pushing the guide over to much hitting the chain on the downward slope. 1 Quote Link to comment
Draker Posted September 9, 2015 Author Report Share Posted September 9, 2015 It's worse now. I'll get new video some day. It's not normal. Quote Link to comment

datzenmike Posted September 9, 2015 Report Share Posted September 9, 2015 Try the engine running with the fan belt off. Quote Link to comment
Draker Posted September 9, 2015 Author Report Share Posted September 9, 2015 The longer you wait the more metal shavings go in the oil. Not if it's parked. 1 Quote Link to comment
datzenmike Posted September 11, 2015 Report Share Posted September 11, 2015 Did you try it with the belt off??? This eliminates belt, alternator and water pump bearing sounds. 1 Quote Link to comment

I have done nothing but walk past the car for the last few weeks. I feel like I've isolated the sound pretty well with the stethoscope. It's not a grinding noise. It's a timing chain noise.

KoHeartsGPA Posted September 12, 2015 Report Share Posted September 12, 2015 I wonder if a broken tooth on the crank sprocket would produce such noise.... Quote Link to comment

Process of elimination. Do the easy simple things first. If you remove the timing chain cover and find nothing obviously wrong (because that's all you'll be able to do is look) then what do you do? I've seen weird things that made no sense before. Like a distributor that instead of the timing advancing it retarded as it revved up. 1 Quote Link to comment

Like a distributor that instead of the timing advancing it retarded as it revved up. I already pulled the valve cover and ran it. The result was oil splattered all over my engine bay followed immediately by a trip to the car wash to clean it. lol. The chain was not flopping around and there was no sign of anything loose. I looked back through the thread and I guess I didn't post those details in here. It's possible the oil pump/dizzy shaft is making some funky noises down at the crank. The sound is 100% coming from the drivers side by the front cover. Not the water pump, not the alternator and not even on the passenger side of the front cover. But I do totally agree with you and value your feedback. It is likely something weird. It has me puzzled.. but it distinctly sounds like a timing chain noise. I wouldn't even be concerned, except for it seems to be getting worse. Quote Link to comment
datzenmike Posted September 12, 2015 Report Share Posted September 12, 2015 Not good. Well it will have to be obvious like something loose or broken. Crank bolt tight? Did I ask this yet? It holds the oil slinger, spindle drive and chain drive snug on the crank. I think 100-120 ft lbs? 1 Quote Link to comment
Draker Posted September 12, 2015 Author Report Share Posted September 12, 2015 Yeah, it's tight, and torqued. Not good. Well it will have to be obvious like something loose or broken.

datzenmike Posted September 12, 2015 Report Share Posted September 12, 2015 Look on the underside of the water pump behind the pulley. There's a weeping hole. Is there any indication that it's been leaking any coolant? If the seal fails, this lets the water out so it doesn't get into the bearing and seize it. It will eventually, but it's assumed the owner will find this first and replace the pump. You have to take the pump off anyway to remove the timing cover. Just give it a spin, see if the bearing is iffy. 1 Quote Link to comment
Draker Posted September 12, 2015 Author Report Share Posted September 12, 2015 Bearing is tight and spins good. No signs of failure here. Quote Link to comment
