Technical He's got some SBC woes

gives a general idea, anyway...

 

With a drill running the pump with modified dizzy and starter spinning engine - # 1 and #2 get oil up top before 7&8 but 7&8 oil more. Weird

 

The wide rear cam bearing with 2 holes was used from 1955 to 1963. When using these year blocks it is easy enough to just modify the block instead of the camshaft.

 

You stated the drivers side rockers have plenty of oil and it is only the drivers side that has oil problems.
I would also check the distributor for a drilled hole in the part that connects the lifter galley together. I've seen people drill a 1/16 hole to oil the bottom distributor bushing, and then I've seen someone that drilled a much larger hole that basically let the oil bypass back to the oil pan.

 

Who said that ?
Extreamly low oil and equal both side
Passenger side valvetrain is noisy but only when at operating temp.
#8 intake has a pushrod rotational problem.

 

might have these in it

I do not have the answer, but a story. Running our Dragster, Aluminum Donovan Block, copy of a S.B. Chevy. Launched at starting line and broke the Rear End, zinged the Engine to the limiter (8400) at the hit. I am sure the Engine went much higher than that. Fixed the Rearend and discovered 2 Blown Head Gaskets. Repaired the Engine and fired it, oil pressure normal, then low pressure, then normal pressure, WTF? Changed gauge (Mechanical) same. Put it on Trailer, take it home and teardown, #4 Cam Bearing was spinning in the Block. Sent back to Donovan for repair, bored bearing hole to take oversize Cam Bearing, back to normal. I always thought that was a strange problem for over revving the Engine. I know that this is not your problem, but Cam Bearings can cause all kinds of strange problems and they are a bitch to diagnose without tearing it down. Good Luck in getting this sorted out for your Customer.

 

no help at all, but fun to talk about, many years ago, a friend of mine did the same thing (roughly the same rpm too) street racing out on Latimore Rd. (betting FEDman knows Latimore well...), in a pretty healthy 350 (ported turbos BIG erson solid) 4 speed grey primered Beaumont. Broke the rear, zinged it to the moon, and the front balancer exploded, pieces punched holes in the front frame rails. I was there (are you lurking Brad??)

 

Misread earlier post.
Left side doesn't clatter? Use ZDDP in oil? Running oil pressure when cold? Pressure when warm? Where is pressure being taken from? Front above timing cover if the plug is there is the best spot, second is next to distributor, and the worst place to take it is just above the oil filter housing.
What are the spring pressures? Too high they can collapse a lifter and eat the face of the lifter and the lobe of the cam. Is there enough room from coil binding the spring?
A problem I've also seen before is are the lifters correct for a SBC? Sometimes if using another GM lifter for say a Buick, Pontiac, or Oldsmobile the recess for oil flow that connects the galley together can be in the wrong spot which when at max lift can uncover the galley letting oil escape, this can be checked with distributor out and turning engine over by hand and looking at the lifter in the bore.
Does the engine look like it was assembled with White Lithium Grease? This grease can accumulate and block off oil flow in al sorts of places.
Have you looked to see if the above pictured oil restrictors are in, these are notorious for being bad on hydraulic lifters, some people use the older style restrictors that are under the rear cam bearing in the 2 lifter galley holes, the holes would be tapped and set screw with hole installed, kind of like what is done for the Ford 351C.

 

Well you know the cam lobe is history..

 

whats wrong with hillbillys if I go on a trip and get stuck I want the hillbilly with me not you he'll gets us home and that's a fact!!

 

Curious what the solution is...Good Luck!

 

funny, I thought about this early on, but thought " naw, no one would be stupid enough to do THAT". Be pretty funny if that's what it turns out to be, it meets all the symptoms...

 

On July 14 I mention oil restrictors.
Latimer Road. Wow I hadn't hurd that name in a long time.

 

George, I know Latimer Road today. Back then we were South Vancouver Punks, Kingsway was our "Track" My wife was at Latimer Road in her 68 Chevelle though.

 

jesus, her maiden name wasn't Fletcher, was it? Viking Way was my 'home track" for a while there...

 

Finn Road was my home track lol

 

No... Not Fletcher, Viking Way? January 1975 in a snow storm I drove my 53 Chev Pick-up that I "Built" out of my Dad's shop on Vulcan way & turned right on to Viking Way the day I got my Drivers License. What a small world. great memories for sure.

 

Yeah I've seen this on more than one occasion, and yeah people can be that stupid. We once had a guy trying to build up oil pressure in a SBC race engine by turning the engine over with the starter. They were down in the garage and we were up in the shop and it was taking quite a while to build up pressure. Turns out they forgot to install the distributor, and these were guys that had been around the race car block a few times.
I also think the rockers should be looked at being they are roller tip rockers. The balls might now be burnt with so little oil going to them.

 

I think more than a few people have mentioned that.
I also think pictures might help a little bit.

 

man, I will NEVER forget the first time I went to Viking. I heard about it from a couple guys from Surrey (anyone remember Ted Lockoff??) that I met out at 200th, when we were using that street a block south of the Rose & Thistle Pub(I was living in Maple Ridge in those days), heard it was THE place, and Sunday night was the night. So we drive out there at 1 am on a sunday night (had to work the next day) we turn onto this street in an industrial park. The street is literally COATED in rubber, but it looks totally deserted, no one in sight. I am driving down the street swearing under my breath, thinking " what a total bust, must be the wrong night" when my buddy shouts "STOP!! BACK UP!!" So I back up and look to my left, and there are about 75 cars, car trailers, some of them with Washington plates, and several hundred people down between this row of warehouses! Man, Id never seen anything like it, there were a couple guys from the GVSM walking around with walkie-talkies, I found out later they had a couple of "spotters" in a van at the end of the Knight Street bridge, and another guy east of the south end of Viking. We were there until about 4am that night, and it wasn't much later I became a member of the GVSM. What a scene that was. If they ever invent time travel before I die, I'll be signing up and heading back to a hot sunday night in 1982, just set the coordinates for just east of the Knight Street bridge...
I'll just add this as well. When I was about 10/11 yrs old, my cousin Jack, who had a '69 Camaro with a swapped in L-72, took me to the street races up Galardi Way. By the time I was old enough, the street racing had been shut down up there, but it was pretty hot and heavy in 1970/71 when my cousin was taking me up there...

 

Please forgive this off topic question. I t does however relate to oil pressure and a little levity at this point seems to be in order. My Dad and cousin were building an engine (probably SBC) for dirt track racing when my Dad had the bright idea to "stretch the spring in the oil pump" to increase oil pressure. My cousin who is a mechanical wizard, strongly cautioned him not to. I am told that when they fired it up it "blew the valve covers off the heads and oil went everywhere." I have always half believed this story and don't want to try it myself. My question is: Is this possible?

 

NO!

 

So much for the levity (my cousin is so wonderful)

 

I'm sure that story has been well seasoned for taste.

 

Few rockers with extra heat treating-
Progressing left to right more heat till its all blue on the right.
These are PWR rockers.
Most Every roller tip is shot now.




Geometry off & Push rods too long - 8.100



Beehive springs would have been a better choice here.


More coming later

 

Hello: I'd like to order a peperoni pizza and a pepsi while I wait to see what happens with this engine.....

 

Here's at least part of the fuel delivery problem fuel pump rod is missing 1/4"

Fancy Huh? Ever wonder what's inside one of these light weight rods? The rest of it is in the engine someplace

Compared to a regular old GM steel rod.

 

Oh man, this is NOT going to be pretty...the oil that is there really looks cooked. You already know, this sucker is wasted...

 

Nope, its pretty ugly!

( Sausage and pepperoni for me )

way less than 500 miles, its probably closer to 200 in all actuality.
The bright side is That's way better than Top fuel longevity and budget wise especially.

On the oil, I drained what was in the pan while the engine was in the car. I dumped 4 quarts of fresh oil in it once it was on the stand.
