Lost ALL oil pressure with a loud clicking.

[JMiller]

Ok, while i was driving last night doing maybe 80mph in 5th i started to hear a faint tapping sound, i was beside an old truck so i assumed it was that and sped up some to get away from it. Well i got away from it and still heard the sound but it started getting louder and louder until CLACK!!! really loud then a constant loud clacking (sounded like rod knock). I parked it asap and got it towed home today and i just wanted some opinions on what to do before i just tear the whole thing down, or buy a short block or maybe a long block. All helpful opinions welcome. Keep in mind this is my only car and i work full time so the cheapest and quickest solution would be best. Thanks. Also the is no oil leaking anywhere and but my dipstick went from full 2 days ago to the bottom notch afterward.

Drain the oil and see if there are any signs of bearing material. I would also pull the oil pan to see if there are any damages.

Also, check if the timing marks are spot on.

I would deff drop that pan.

OK, pan is getting dropped Saturday when im off. Also forgot to mention the oil light started flickering and then the loud clack happend and the oil light stayed on and my oil gauge read 0(zero).

Sounds like your oil pump crapped out or you spun a bearing...or possibly both.

Hope that the sound was your lifters ticking from oil starvation and not a bearing spinning from it.

When I drove my car without oil for about 2 blocks it was clanking and clacking like crazy. I thought it was just cold oil (30* out that morning). Then I noticed no oil pressure. Oil filter came loose. Refilled it (BradPenn 20-50). No issues to this day...

So pull the pan. If its still full of oil then the pump may have died. If its empty, find the leak, fix it fill it and start it up.

I cranked it today for 10 seconds and the clicking is coming from the top(Head/valve area) and sounds like lifter tick.

 

[stuckwithgsx]

Is lifter tick noticeable from cranking?

Kind of sounds like valve (s) to me. Did you check the timing belt marks? May have skipped a few teeth?

 

[JMiller]

I guess i should have put cranked and started and ran normal except for the loud ticking for 10 seconds or so.

I would pull the valve cover and check the lifters one of them could have collapsed.I would check the timing marks too.Do you have balance shafts or are they deleted?

 

[GSLENK]

you can really hear something over the starter motor? sounds like a main bearing or oil pump etc... I doubt its a lifter or timing issue. and I cant see a bad rod bearing sending you into a no oil pressure zone that fast. also I couldnt hear lifter ticking or spun rod bearing during starter operation. and I most cetainly couldnt hear anything manually cranking by hand. My vote is with oil pump or main bearing.

My last car had collapsed lifters, and a spun rod bearing, i know both sounds intimately.

MAybe you could post a sound clip to you tube. I sure running it at idle shouldt do further damage unless u have metal chips everywhere....

On the note of you pulling the pan, you might as well check all your rod bearings while you are down there, its not hard at all... just be clean and organized, label which way they came off, where they came from... should have no problems, unless of course you find a problem.

I experienced something similiar when I first bought my GST and it turned out to be that my oil pump had gone bad. I would say listen to everyone else on here and at least drop your pan and see what you find. Might not be a bad idea to check your oil sending unit and make sure that didn't crap out on you. That little thing might be the whole issue. Good Luck!
