Automatic car with the sport package. lol

 

I probably won't pull the motor until Sunday. Is there anything I can inspect in the mean time? Drain the oil and look for metal particulates? Pull the valve cover and look for the same?

 

Against my better judgement, I gave the car her last turn of the key for a while so that I could document the noise.

So, get your tissues ready:

 

<p>That's just lifter tick! :(</p><p>Sad day.</p>

 

I'm really not thinking rod bearing anymore. Maybe bent rod? I'll compression test it tomorrow after I go get the new motor.

 

Just pulled the plugs and one had some oil on it.

When turning it over while the plugs are out in flood clear, I don't hear any abnormal noises.

 

Pull the valve cover, see if you spit a shim out. Also spin the motor over and watch, see if any of the valves are not fully closing like they should.

Kinda sounds like you bent a valve. Does is run fine other than the noise? If so, not a valve.

 

Didn't get on the gas any the 1mi i drove it, but it seemed to drive normally.

EDIT: plugs

 

Your plugs look fine.

Do a comp test first, see what that shows.

Then go make a better video. Long vid, startup, idle, rev, drive it, boost it.

Cold startup vs hot startup would help a lot to diagnose this.

 

If you happen to spit a shim, it would run fine, just make bad noises. Comp test wouldn't really show this either. Pull the valve cover and start looking.

 

I'm still going to go pull the motor in the junk yard first thing tomorrow, as I can always sell it and profit. After I get back and eat lunch I'll do a compression test, then pull the valve cover and investigate.

 

If you pull that motor and then find you spit a shim on the current motor, will you hook give me a good deal on the VVT head?

 

I'm embarrassed to say I don't know where these shims reside to begin with.

 

Basically when you pull the valve cover, you'll see the cams and cam lobes. The cams spin, and the lobes will rotate until they push on the "shim". The shim pushes on the lifter. The lifter pushes on the top of the valve. This is how the cams actuate the valves. If it spits a shim, the shim will basically fall out, and the cam lobe would now be hitting the lifter instead of the shim, and the shim would be laying inside the head somewhere. This would normally only happen during extreme valve float, usually caused by an overrev.

This is unlikely, but possible. Worth checking before pulling the engine.

 

Took 95 minutes to pull lol. Exhaust manifold and intake manifold will be for sale, and I'll decide about the head later.

Speaking of which: Opinions. Should I wire my MS3X for VVT, or swap my 99 head over? I took the three plugs for the VVT.

 

VVT! Do it.

 

So compression numbers 17 days ago, Cylinders 1-4
180,170,175,175

Today:
158,151,60,125

The cylinder would keep climbing if you held it for like 15-20 seconds, I stopped around 80 or 90. I put 60 though, because things really creeped after that.

 

Hmm... Pull the valve cover, if you don't see anything pull the head or motor.

 

Started to and it started raining. Once it stops I'll head back out. I need to buy some rubbermade bins and stuff to put all this in so they don't get **** all in them.

 

Everything looked okay to me.
