engine clicking, car died and boiled over.

[ianGST]

I have a '97 GS-T with some basic mods and a 14B turbo.

The past few days, my oil pressure had been lower than usual and the car developed a ticking or clicking sound on my way home from work. It sounded like metal on metal clanking and seemed to only happen between 2,000-2,500 rpms, and it sounded like it was coming from the valve cover area. If I had to pick a side I'd say the flywheel/passenger side. The next day I did an oil change with 10W30 synthetic oil and used some Lucas stabilizer as well (I had read on here that the noise may have been lifter tick.) Doing so made the noise a lot less noticeable and it actually went away for a while. I let the car sit and bummed rides for the rest of the day.

Then this morning I needed to use it to pick someone up from the airport and on the way in the car had no power past about 70mph or so. The car felt extremely weak and the clicking noise had come back. The oil pressure and temperature gauges were fine. Once I got off the highway and pushed the clutch in, the car died and wouldn't restart. I pushed it into a parking lot only to find that it was boiling coolant out - fast. About 30 minutes later the car started fine under its own power but still made the noise, so I left the car there and thats about where it sits right now. Any ideas would be great!

Also - it only seems to make the clicking/ticking/clanking when I'm on the gas. Not even accelerating the car, just *on* the gas. Even the slightest pressure on the pedal.

Thanks!

Well first off, I would never have put in that oil stabilizer. There might be a video on the net still, but if not, get a friend at O'reileys to do this:

On the little lucas display have them find a way to hook up an electric drill to the little hand crank, then turn it up for a good 2 minutes. Then take a look at the oil with the Lucas. Foaming maybe?

Definitely not good for your motor. As far as the rest? I don't wanna speculate, so I'll let someone else chime in.

rods maybe?

Hey everyone!

Finally went to where I store the car and made a video. Hopefully someone here can tell me if this is a problem in the head or if its bottom end or shed some light on what it is. Thanks!

Well i've heard that sound before and it sounds like rod bearings.

This sae thing happened to me



I spun a rod bearing it started to knock, temps went up then engine shut off on the highway. I pull over and its Red Hot.

Spun a Rod bearing and now im rebuilding the motor

Yeah so it seems to be a rod bearing I guess. If I pull the pan and see fine metal bits I'm probably going to start tearing into it. What should I be looking for on the crank to determine whether or not it needs to be replaced? I'm under the impression that its possible to replace the bearings by themselves, if its caught early enough. I don't really want to dump much more money into this car at the moment so I'm not interested in a full rebuild. I can let the car sit for as long as I want. Thanks!

 

[GloriousDSM]

Yup pull the pan. Most of the time there will be bits and shavings somewhere in it, especially if it shifted and got shredded.

Here is how mine looked after so its very noticeable.

hope that helps some.

If it's caught early enough you may be able to just replace the bearings but i wouldn't hold my breath. If that's it then the crank probably has some marks on it and you will need to have a machine shop look at it.
