I left the oil cap off the C4. It runs like shit now. Speaking of shit, I just stepped in two separate mounds of dog shit to make the day even better! Now my car gets to sit under a cover for a few years until my broke ass makes enough to buy a rebuilt engine. I'm even angrier at myself for ruining something that's been in use for nearly 30 years.

Oh holy shit, man. That's the pits. You're sure there's no way to salvage the engine and get it running?

I did right after I found out. Even rougher now...

It's running, but it feels like it's way down on compression and seems to knock a bit.

That's unfortunate. Is it possible to flush the engine and get any dirt, etc. that's in there out?

I forgot the cap on my civic once... I would have never noticed except on my first right turn I heard a thud then saw something bouncing on the road behind me (my cap). I've almost killed a few engines now...

I did the same during my internship at a Volvo shop. Several gallons of brake cleaner and some fresh oil later it was back on the road running like a champ again. Which leaves me with the question: Exactly how much oil did you lose before finding out?
![]() 10/17/2014 at 17:51 |
|
Think of it as an oppo-tunity. It's Tdi Time, baby...
![]() 10/17/2014 at 17:52 |
|
Whoa whoa whoa, back up. How much oil could you have lost out of the open cap? Literally, how low was it on the dipstick? Even if you lost a litre and ran it like that for a few hours, it shouldn't "knock a bit" and "feel like it's way down on compression". My feeling is that there is another, simpler problem such as timing out of whack or a fouled plug.
![]() 10/17/2014 at 17:56 |
|
I agree, it really sounds like something else. If it sloshed out the underhood area would probably be a mess.
Maybe a vacuum line or something?
![]() 10/17/2014 at 18:01 |
|
The oil filler cap is actually in the cylinder head, though.
![]() 10/17/2014 at 18:01 |
|
Yeah, cap is in the cylinder head.
![]() 10/17/2014 at 18:02 |

The cap is actually in the cylinder head, so in this case yes.
![]() 10/17/2014 at 18:03 |
|
Yeah, something like that. Or if he hosed the oil off of the engine bay, and now the distributor's moist.
Sleep on it for a few days and come at it with a fresh perspective, or get a second opinion before condemning it to a full rebuild.
![]() 10/17/2014 at 18:03 |
|
If you ran it low enough to cause damage, I would think the symptoms would be more obvious. You might just be freaked out and noticing things you didn't notice before. Only way to tell if its down on compression is to do a compression test.
![]() 10/17/2014 at 18:06 |

Fuck. So sorry to hear dude :(
![]() 10/17/2014 at 18:12 |

You probably just flipped out the FI system by having a massive vacuum leak. I betcha everything is a'ight. I've never seen an oil cap kill an engine and I've seen a number left off.

![]() 10/17/2014 at 18:29 |

Yeah, it just feels like there's no compression so that's what I'm planning. On doing.
![]() 10/17/2014 at 18:35 |
|
What does that have to do with it?
Besides, I've never seen any engine with the oil filler cap in the cylinder head, and definitely not on a small-block Chevy. It's in the valve cover.
![]() 10/17/2014 at 18:36 |

What? Got a pic of that? Seems like a first to me.
![]() 10/17/2014 at 18:37 |

This is the absolute worst kind of news. 350 blocks are cheap and plentiful, but that doesn't mean it isn't a big job to do.
![]() 10/17/2014 at 18:45 |
|
That. Fucking. Sucks.
The way I see it, you've just gotta view it as an opportunity. You can either save up for a new short block (last I checked, a new GMPP 350 short block was about $1700-1800). Or, you could save longer, and go for an LS swap. Either way, your Vette will emerge stronger than ever!
![]() 10/17/2014 at 18:49 |

Well, it's the cylinder head cover, and the valve springs and everything are underneath...
![]() 10/17/2014 at 18:52 |

Low oil can't cause low compression. It can make bearings knock and seize though
![]() 10/17/2014 at 18:53 |
|
I meant to say valve cover with the cylinder head components right there . But the point still stands—there would be tons of oil coming out of there not to mention that my car burns lots of oil
![]() 10/17/2014 at 19:07 |
|
If the compression is low, it would have a hard time starting.
![]() 10/17/2014 at 19:18 |

It does, burns a ton of oil and takes a couple seconds.

It was days, although those were my first assumptions. It just feels like something's seriously wrong.

Cylinder head cover*
![]() 10/17/2014 at 19:24 |

Well, that part of the engine is not under pressure so I don't know how much you would lose.
Can you post a pic? Don't climb out on the ledge just yet. I have a feeling it's something else.
![]() 10/17/2014 at 19:25 |

If you run it out of oil, it'll seize.
![]() 10/17/2014 at 19:44 |

I don't get how all of the oil could escape from here. The plug on the bottom of the pan, sure. But the cap?
![]() 10/17/2014 at 19:49 |
|
There is a chance the rod bearings arent toast. The valves will typically start to clatter first. How long did u have things going south? You can cut the oil filter apart with a hacksaw and check for bearing material in the pleats. You can email me at bnutter@wiseco.com and i can walk you through this over the phone.
![]() 10/17/2014 at 19:53 |

Well, if he ran it, then a lot of the oil could be pumped out
![]() 10/17/2014 at 19:59 |

That's true. I'm hoping it's some crazy coincidence, because in the morning I didn't think that would be the problem but now I'm a bit concerned. I'll send a pic when I get home, thanks for the help.

Ah, it's driving but not well. When I started draining the old oil, it didn't take as long as it should, but I expected a recovery.

Thanks, will do! I appreciate the help, there seemed to be a bit of clatter from the engine bay every once in a while but it was from crappy alternator internals IIRC. It was never perfect but was a solid 130k engine.

"I have this thing that says LS7 in my garage if you would put it in your car."
Wait... yesterday, a guy at a gas station told me to never change anything about my car and I said I wouldn't and I'd be breaking the promise. So no LS7 for me. I also decide to nail it and lay down some rubber pulling out from a stop into fast traffic in front of a tailgating minivan, probably not the best thing for open oil caps...

It seems to me that the oil starvation has kind of screwed up the internals if that's what the problem it. I opened it up a couple of times and it seems that it's just one of those metal hitting against metal things.

If it were a 900, you'd be fuuuuuucked. Biggest obstacle in pulling your engine is probably where to put the engine puller...long nose on the C4.

I did this to my Neon once. The PCV valve was so bad, it actually stopped burning oil and didn't make much of a mess at all at the time. Oddly enough, I would have sworn that it was running better at the time.
Regardless, the cap had just fallen down to the intake, and didn't get completely lost. I felt rather embarrassed at the time.....
Since then, new PCV valve, and no oil burning. Have you thought about replacing yours if you have one?

when an engine runs out of oil the rockets burn up and may be the source of the bad running rod bearings go next so theres a chance its ok if you dont hear a gutteral rod knock especially on startup. '86 and newer were roller lifters if i remember right. Id cut the filter first and pull a valve cover second to look for blued rockers. After that u could pull the pan and look for blued rod caps, but really the filter pleats will show you that.
![]() 10/18/2014 at 09:59 |

Ok, I'll try to do that today then. I have an '85, so no roller lifters but it is '86 and up. No rod knock, which is a good sign.

It's a small-block Chevy. It will be fine.
At the salvage yard, we had a dealer bring us their Cash for Clunkers cars. One of them was a '94 Chevy truck with the 350. We drained out all the oil, put in a quart of that nasty liquid glass shit they were using to ruin the engines, and started it up.
It ran for five minutes. Every time it would start running rough, the computer would kick in and compensate it out. It finally hit the limits of what the computer could take care of and stalled. It would still spin over, it just wouldn't start.
To contrast that, another C4C vehicle was a '98 Windstar. It lasted 10 seconds and seized solid. The '91 Wrangler made it 40 seconds, locked solid. The '93 Intrepid made it 30.

Yeah, I fear it's something like that but my car came with forged pistons from the factory and it would be really hard to crack one of those. I'm hoping it's something a bit less serious...
![]() 10/18/2014 at 21:14 |
|
I mean, it's about as durable an engine as they come; forged pistons, iron heads, simple and rugged design. I thought such extreme damage would be impossible but I still have yet to find out if it's really bad or not.
![]() 10/18/2014 at 21:15 |

I don't know why I kept calling it cylinder head cover. I always saw people writing that instead of valve cover as a new owner and assumed it was a pushrod thing in my idiocy.
![]() 10/18/2014 at 21:17 |

Sounds like a good plan. It already had a mild cam when I bought it, though. What's the main difference in design between traditional and roller cams?

Probably just a ring then. Much cheaper than a piston

Even if it runs like crap, it's still a SBC - it'll run like a bag of crap longer than regular engines will run at all.
