    Re: replaced front crank seal, sounds like no oil

    I guess i am late to this but i have heard a 3.0 make a nasty rattling/clanging sound from the water pump. And coincidentally, a water pump is driven by a timing belt which can cause the motor to sound like no compression if something goes wrong.. Id check the pump when you get into it.

    Dont push the red button.You hear me?

    Yeah, usually when they're doing that tingtingtingting thing the shaft is off center and they're eating the belt and seeping.

    Re: replaced front crank seal, sounds like no oil

    Its hard to type out noises but ive heard something a lot more like a rod knock than tingtingting. It sounded more like rocks in a can when revving. It wasnt as rhythmic as a rod knock but made basically the same noise. My employer at that time used that case to test my guessing powers. I failed on that one. I said it was a rod knock.

    That sounds pretty close to what this is. I got the car towed home. I got a research paper due next monday so I haven't had a chance to dig into the car yet.

    Yeah, the ting is when it's hitting light, it sounds more like gremlins with hammers if it gets to hard contact, it's usually obvious it's coming from that side of the motor though, and you get loads of brass shavings showing on the rad cap from the bearing wearing crooked.

    Re: replaced front crank seal, sounds like no oil

    front cam spins, but I can see the timing belt is a bit loose. It looks like the front cam is about 90* off. Maybe I didn't tighten down the tentioner enough and it was banging back and forth.

    these are non interference engines right?

    Yes, unless you ask the average shop, lots in the trade seem to be misinformed about it.

    Yeah, diamante pistons, 24V pistons or shaved heads can get you anything from light to full interference...

    Personally though I think the valves are pretty damn close and I wouldn't want the belt to let go at 6000 RPM... particularly in an older motor where the wrist pins and rod bearings might be a touch loose. Wouldn't expect major carnage (unless boosting) but could find the heads on a couple of valves are knocked askew.

    Re: replaced front crank seal, sounds like no oil

    My +2 intake valves barely touched the forged pistons with a big cam. I had them fly cut to keep it non interference.

    pulled it apart, the tentioner was set at the lowest position. Reinstalled the timing belt, tentioned it properly this time, and put it back together. Runs good, I just drove it about 50 miles.

    Re: replaced front crank seal, sounds like no oil

    Did you crank down the bolt on the tensioner? I don't rely on the spring, I push then tensioner over with a wrench ALL the way and then tighten it down.

    ya the bolt on the tensioner is tight. Its got about as much tension on it as it can.

    So the tensioner was rattling and making the noise? Sounds like you caught it before it got even more annoying.
