The balance shaft motor I have (its later though) has two plastic lifter retainers.

Re: Pulled the heads WTF pics*
That's kinda why I was thinking about the VIN... if it was a "Goodwretch" replacement, the VIN pad might be blank, or wrong.
Personally I consider the GM rebuilts in the same category as the Jaspers and other mass-builders. They have no vested interest, really, in doing the job right, all they gotta do is get them out the door.

Re: Pulled the heads WTF pics*
Exactly... I took apart a 93 Typhoon here at the shop and it had that exact retainer for the lifters. So that is and can be a "Stock" Part.
I know the engine in thiis 93 I took apart was the stock engine. It was a one owner truck and she gave me all the history with it.
Now the pictures.:
This is signs that it blew the head gasket material or was leaking between 6&4 I do not see signs
between 2&4
This valve is sunk down below the seat. I bet it popped up the hight of the valve/rocker/lifter. The intake valve stem will sit higher than the other two if you look at it from where the spring is.
But that one is definatly sunk into the seat.
I would definatly go through the entire engine. Leave no stone unturned and don't turn it up till it's tuned.
The video you had was just to demonstrate the noise... it was not your engine. (correct...?) Since that was a newer 4.3 in the video.
Wish I had better news.. But good luck with the build!

Here are two pictures of the 93 retainer found in that 93Ty. I just took a few min ago.

Re: Pulled the heads WTF pics*
Right, that vid was not mine. I had a vid but I dont know what I did with it.
I also noticed that the gasket between the cylinders looked blown.
So why do I have a 93 retainer in a 91 truck?

Re: Pulled the heads WTF pics*
Most likely you don't not have a 91 motor, you probably have a replacement motor. Check the VIN on the driver side rear pad or for the date on the passenger front pad (DaveP explained this a few posts up)

Not that It matters but my 92 motor didn't have that lifter retainer pictirued above, it had the older style metal one. They must have made that change in 93.

Send me a freshly rebuilt motor with a big cam and aluminum heads
Thanks everyone. I should just buy a motor from RPM and part out the one I have. We will see what I end up doing.
Yep.. exactly.
Replacement GM crate engine.
Sorry about your luck.
Anything we can do to help?

Re: Pulled the heads WTF pics*
rebuild it and do it right even if it takes some time,put the good heads on it,forget the l35s,save yourself some time and money tunning and base your build of someones that works,I know I have a great 50 and 75 program for stock ecm as well as others do im sure.Pull the motor and just take your time.

Re: Pulled the heads WTF pics*
Thanks for that info Dave... I'd not seen that exact discoloration on my Nitrous SBC stuff back in the day but I was using allum heads and good gaskets. I would like to see the actual gasket off this truck I'm sure it looks like a pretzel from peeling it off the head but it'd be good to see how it looks between that surface.
The old detonation Monster strikes again. Boost won't kill a engine but detonation will every time!
It's all about getting the right amount of fuel with the proper timing with out hitting detonation with the octane fuel your using. Once you have those planets alligned your golden.
I do have a spare block here to build up.

Re: Pulled the heads WTF pics*
020 on the #2 piston should be a clue to what it is. Also, the larger valve reliefs and dish chamfer do not match other posted pics of stock engines. Looks like there may have been a hot spot/burn @ 9 o'clock on #4, which would explain a pinched ring land.

Re: Pulled the heads WTF pics*
What does a new motor have to do with that. Replaced the dash along with it? Probably exempt because of the age of the truck.

Re: Pulled the heads WTF pics*
With the motor being a complete question here, it might be possible that the valves could have been replaced with a set of valves with that "recess" built in. :dunno: Its possible..I've seen some cheap valves with that in them. And I've seen some $$$ ones with a larger recess in them as well. (My bowties have a larger recess, or dome style in them) And not to mention that it looks like all of the intake valves have this. Which if that's the case, I doubt all of the valves were pushed in like this.
Is that area where a lot of gaskets fail and cause coolant to get into the cylinders?
I wonder if rebuilt motors with a really good head gasket will look the same between the cylinders like this. Makes me question blocks that have been bored if this is actually a problem when it comes to blowing head gaskets, or leaking. Considering the area between the cylinders is smaller.

Re: Pulled the heads WTF pics*
I take my comment above back. After thinking about it, and I thought the stock valves looked similar to those with the recess. I went out and looked at both set's of stock heads I have in the garage and mine are identical to his. And I know mine are stock.
Here are my stock 70k heads from my Sy. I broke a ring land on #3, nothing else wrong with the motor. And it in fact still drove great, just wouldn't build more then 12psi.. I sprayed the head with some break cleaner to give it a little more detail when taking this picture not 5 min's ago.. So his heads look good.

Re: Pulled the heads WTF pics*
This engine was definitely replaced as many others have already stated. Im also willing to bet that it was from a mass produced remanufacturer like Jasper or others.
I worked 10 years for a large engine remanufacturing facility in PA perfroming al aspects of machine work as well as assembly and dyno testing. Ive seen plenty of warranties and damage in my time there. Ive literally built over 3000 engines. Alot of things I see here are showing rebuild especially the 020 in the piston and the use of any block that will work. Very common to have this in a large reroduction evironment. There are also a few different styles of rods. Im willing to bet the dotn match what usually came in a 91 SY just like the lifter retainer hold down. Other things to look for are an aftermarket timing chain, oil pump, lifters, and pushrods as these are all items that commonly get replaced on a stock rebuild. Also look for number stamping on the oil pan rails or the section at the top of the block where the intake seals. These are areas alot of remanufacturers will stamp. Also look for Serial ID tag glued to the block somewhere as well as melt away discs on the block or freeze plugs. These will melt if the engine is overheated. Its for warranties.
Now, as for the engine with reagrds to diagnosing a piston slap vs a lifter noise, they will at times sound similar. However, piston slap usually comes around when you rev the engine and let go and the engine start to decelerate. You see the load is on the piston while the RPMS raise but when you let off the load goes away and the piston has more opportunity to "float" in the bore. A lifter noise, however will most of the time be there all the time and be consistent with the RPM on acceleration and deceleration. Looking at your pics, I agree with Dave P in that you have detonated that cylinder. Piston slap occurs on the skirt of the pistons. Your scratches are on the side. This is most like due to detonation where fuel/air enters the chamber. Dont be surprised if when you pull the motor apart to see the area above the top ring land appear to be "smeared" with lines in a vertical pattern. And you intake valve does look sunken often refered to as "tuliped"..these are both great indicators that detonation was your worst enemy in that cylinder.
Hope this helped.:tup:
