I think I blew my motor - LotusTalk

rskdsk · 01-02-2013, 05:56 PM

I was testing out some new spark plugs, but not doing anything abnormal. second gear, gave it gas, boost hit 10 psi, shifted to third, car died. Was able to start engine but it ran like total crap ... limped home. Pulled the plugs and 3 were carbon covered, the forth was clean. I did a compression check on the clean cylinder ... nothing ... no movement of the gauge at all. Other cylinders at 215 psi. No water in the oil, engine temp was normal while running on 3 cylinders. I am guessing I lost my rings.
Not sure what my next steps are ... looking for someone in SW FL that can do the rebuild.

You could do a leak down and that would tell you if it was rings or valves. I'm guessing valves (valve). Either way, it's coming apart.

If you hold off on running the engine, you may get away with having the head rebuilt. Pull the head first, before you rotate the engine any more. Pulling the head will tell the full story.

Did you hear any metal clunking around in there? Possibly dropped a valve, bent a valve, lost a ring, or just blew chunk off the piston. Like Addertooth said, take the head off. That will tell you everything. If it's just the head that is jacked and it didn't take anything else out with it, that's an easy fix. If the cylinders are jacked... well... that is going to suck big time. Time to sleeve that block or have it punched out to a 2.0 stroker.

I did not hear anything banging around in the motor and I did drive it on three cylinders back home ... about 3 miles. Since I already did a compression check and all cylinders are normal except one which is completely dead ... I am guessing my next step is to take the head off and see what really happened.

rskdsk · 01-03-2013, 01:56 AM

I have been search for a thread on taking the head off ... I know I saw one, but now I can not find it ... any help?

addertooth · 01-03-2013, 03:57 AM

Changing a head gasket?

rskdsk · 01-03-2013, 06:52 AM

That is not the one I was thinking ... there was someone who took lots of pics. However that link makes me think I should pay someone ... I do not mind the work, but I want it done right.

BTW I did look down into the spark plug hole, off to the right side of the hole ... I think I see the edge of a valve ... meaning I may have lost the valve ... not the rings. I am guessing if I pull the valve cover I may know for sure.

I bet it is the valve, if there was a chunk in the cylinder well you'd hear that'

Not always true. My friend and I were coming back from lunch the other day and all of a sudden something went pop and we were cruisin on 3 cylinders. Massive amounts of smoke, no metal noise clunking around, obvious serious loss of power. We limped it to his house, pulled the valve cover, and took out all the spark plugs. Cylinder 4 spark plug was crushed and zero compression. The next day we took it up to the shop and dropped the engine out only to find a massive chunk of the piston missing and 1/2" of the ring gone. We didn't hear anything when it blew up and we drove at least 2 miles on it.

Yes if it goes under the piston could go in pan

I posted some pic in another thread ... it is the valve. I did not hear anything, car did not smoke, plug was fine ... I am hopeful that the damage is limited

I don't think so.
