motor doesn't sound pretty (vid)

[KRRZ350]

Quick rundown- 2g w/120K, recent 1g head, problem arouse after sitting for 5 years. Fresh oil & plugs. I say otherwise in the video but when you get underneath it almost sounds like a knock as well, but it's hard to tell.

YouTube - 2g dsm awd tsi top end noise, maybe lower knock as well

I'm working on this car for someone else, and I really don't want to have to get into this motor right now, so it's not looking good. s

I think my next step is to screw a good mechanical gauge into the head right?....

BUT that damn allen plug is NOT coming out. So quick question- can I tap into the other small allen plugs to check pressure? There is a gazillion on this head I'm sure one will come out easy. I really can't run around all day to try to find something to adapt into the larger bolt (The one that faces the passenger fender, on the same oil port as the small allen that faces the grill.)

After watching the video what do you guys think? I was scared before I even started it that the oil pump had lost it's prime, I'm not a dsm owner and I know stock gauges suck anyways, but how does it look to a dsm'r? It goes higher when revved obviously, but slow- I'm assuming it's just the delay in the gauge.

If the car has been sitting for 5 years. My first guess would be lifter tick or a collapsed lifter. Pick up a mechanics stethoscope and try to pinpoint the location. You can also use a long screw driver or other similar objects to try and find the location.

Did you prime the engine before the first start up?

 

[KRRZ350]

No I didn't, just read the writeup here on it though & I'm going to do that, if it's still there I'll rip the rocker cover off, I think you're right on that one, completely forgot these motors aren't cam on valve AND have notorious lifter problems- oooops.

F F F F F F F F! I F hate these F bomb F cars pieces of F S.

I think I found the problem no?

Looks good to me, whats the problem? Sounds like a lifter to me...

Yup. It's a lifter. Timing looks fine.

That notch that you took a picture of is for IGNITION timing, not mechanical.

Toss some Lucas in there and see if it clears that up. If not, then replace the lifters with 3G revised ones and you should be golden.

Note : Be sure, if you haven't already to get that timing belt changed if it's been sitting for 5 years.

That notch might be for ignition timing but I'm pretty sure it still lines up with T when the #1 is at tdc. I'll put the cost of a valvejob on it.

Checked the lifters, they all appeared fine (and they are all less than 300 miles, owner claims they are v3 but I have my doubts based on pics). Good advice there though, I put lucas in at the oil change, allthough only a touch, not a big fan of it.

I reset the belt using the proper mark on the crank gear (well, the signal plate and the protusion on the block- it's a 2g), which coincidentally put the above mark right at T instead of like 30* BTDC.

Started the car up, sound completely gone. Ran compression test & got 160-150-90-90. Heads coming off tomorrow, beleive me I wish it wasn't so, if one of you can make me look like an idiot and prove to me that that mark doesn't line up with T @ TDC or that the timing belt marks aren't meant for TDC then I'll paypal you $20.

AH! I see, I forgot that pulley has a locating dowel that could have EASILY been switched in the past, NOW I see why 2 of you were saying that. So FTR I went by the true timing mark under the cover, and this one had it's dowel in the correct place, timing was jacked up

Sorry I doubted any of you, I take back that $20 PP offer since I made myself look like the idiot first.

you have to turn the motor over 4 - 6 times for the bottom end to line up

 

[GsXdSmKingGsX]

Timing is spot on. Belt looks good. Its just terrible lifter tick. Speedfactor 3g lifters are your new best friend

 

[KRRZ350]

You sure you're not thinking of belt marks? Or turning the motor over 4-6 times to ensure that everything STILL lines up? Most 4-strokes I've worked on turned the crank twice for every revolution of the cams......

OK a 3rd person saying the timing looks spot on in the pics, now you guys have me going WTF. I'm going to double check everything again. The sound did instantly go away as soon as the belt was reset though, and resetting it brought the pulley and gear crank marks to tdc.

Damn you guys! Had me doubting myself! It's cold out there!! Just went & pulled the crank pulley off and confirmed my findings: At least on this car, the timing light marks on the pulley are correct for TDC. Engine jumped timing, resetting belt made sound go away, low compression on 2 cylinders after the sounds I heard = bent valves.
