on my GM . 1GCEK14TXXE118547. Model K15903. 1998
On the way home from work pressure gauge started moving up and down. I pulled over and heard . loud clanking noise then died…
Where do I start….I want to try and fix myself…..ThanksI am sure someone will be along soon to offer some expert advice to you, I am not an expert so take my opinion with a pinch of salt. It does not sound good does it? What you describe, to me, sounds like a catastrophic failure on an internal engine part, if you do not know where to start then I would suggest you might be better having a suitably qualified person take a look. What you have described certainly does not sound like something you can cure with a new bolt on part, my hunch is you are into either a complete engine re-build or a new engine install 🙁
As said I am by no means an expert so check back and see who else replies 😉
Thanks… I knew it wasnt gonna be a quick fix. We can do it . Just need some assistance. The sound came from up top. lifter / rod area
I am really no expert and am sure someone will be along soon with some “proper” advice but in the meantime if the sound was from the top of the engine then I suppose the first logical step would be to get the valve cover off and see what you can see 🙂
It would have been easier if you had just said that it was a Silverado with a 5.3. That VIN is for a 1999 by the way.
Does the engine start?
How many miles are on it?
Did the rpms fluctuate when the oil pressure fluctuated?
Did you lose power before it died? Or did it just abruptly die?First, I wouldn’t run it.f it lost pressure and made a clanking sound, something internal is wrong. It may be time for an engine rebuild, but I would like to hear your answers to “thisisbuods” questions before we come to any conclusion. I would not try to restart it myself, I simply would try to rotate the crank to see if it has seized.
He never said it lost pressure though. He just said the pressure fluctuated. I was more wondering if he had tried to start it. I wasn’t recommending that he try to start it.
A clank could be something as simple as a belt.
Turning it by hand would be a good idea. Just make sure you pull all the plugs first and put the tranny in neutral.[quote=”thisisbuod” post=135667]He never said it lost pressure though.

We don’t know how far his oil pressure dropped, we also don’t know where the RPMS were. We need more info regardless.Another classic example of people asking others for help when they are way too lazy to even bother writing up more than 3 lines about their vehicle and the major problem it has.
If they are too lazy to provide a decent and comprehensive write up, they can work it out for themselves.

It can be a pain trying to get all the info needed, but not everyone is accustomed to using forums like this. And if you don’t work on cars professionally, you may not know what information is pertinent.
Well matter of fact I have been busy. This is my first few times on this site….To answer your questions. It won’t start. Has 226K miles.Don’t remember looking at the tach but it was idling when it locked up.It had been running fine (no loss of power) It died abruply. Tell your buds theres a difference between busy and lazy…Theres too many other places to ask my questions. Tell Ericthecarguy this type of attitude does’nt let this site shine. Thanks again
Unpleasantries aside; Does the engine still have oil in the sump? Try turning it by hand (after pulling all the plugs) as we suggested earlier. If it doesn’t turn try removing the belt and turning it again.
Step 1: confirm that there’s oil and that it’s at the proper level.
Step 2: grab a ratchet and stick a socket on the crank bolt and see if it turns. if yes step 4, if no, step 3.
Step 3: if the crank doesn’t turn proceed to replacing the engine.
step 4: confirm function of the oil pressure sending unit/switch.
Step 5: Using an oil pressure gauge, remove the pressure switch and test the oil pressure. If there’s no preesure there’s an internal failure.
From your description of loud tapping followed by the engine stopping my vote is that the engine is done.
