thanks everybody ...ive have seen the oil path....just double checking that there is no typo.....ie that it can be trusted...lol you know .....cuz you never really know the whole thing seems backwards...to whats usual but then hey go figure right......

hh65flyer-thanks for confirmation ...thats what I needed....you just never know...


ihscouts-"check socket for missing pushrod socket cap (common)" I am really interested in this comment I have been looking all over for a picture of this socket.....I am gonna run down and take a pic to post right now cuz every write up and picture I see is of some side angle ...?? showing no wear at at ......next to text saying to look for wear!!!

 

ok i have confirmed with bp that i have after market rockers....which have cast push rod seats im ok with this and it confirm that she been worked on before also thanks everybody post more pics later lot of cleaning to do :0

 

also figured out that the black dot wasnt metal at all just really tough grot stuck to the flat portion of the push rod end.....just didnt want to be overly agressive...oh im learning so much......

 

There are actually two things to check on the rockers. The socket and the button. The pushrod socket is stainless, they are crimped in and have been known to disappear. The stainless button on the other end of the rocker contacts the valve stem and will also make like magic and disappear. It's not so much a design flaw as is keeping the weight down which makes little sense with the use of solid pushrods but then again that's LR for you......

Glad to hear you got the black dot figured out. I've sat down to reply to you several times only to be interrupted every time........one of those days. Keep up the good work.

 

so my heads are slightly warped i guess took them next door to shop that had a straight edge after polishing them up with a scothbrite pad.... and found there to be .03 - .04 or so gap towards the middle....oddly both sides were like this and it does make me wonder if his straight edge was not straight....at any rate i guess i will take them into machine shop and have them checked ..... we checked it on both edges of the straight edge and there was light coming through...and same gap measurements so i guess its probably real ay? Will find out more tomorrow

was also able to get many of the tappets to come out today....no depressions at all on these so yeah..yeah ..yeah... and I contribute much of this to Amsoil with Zinc...they look perfect actually....all but one which had the slightest of wear...i mean very slight .....I was able to inspect about half of them today...by turning them slightly it seems they are easiest to slip in and out with oil hole facing the outside of the engine /wheel well side.....and slight twisting....

 

here's da page with the head "flatness" specs from the overhaul manual

 

Well then, I'd say if you can remove the lifters from the top of their bores they are doing good because high mileage ones will be mushroomed to the point where they'll only drop out the bottom of their bore. I didn't know about the Amsoil.....bit of a game changer.

 

One way I have seen to check your lifters for wear (concave/convex) is to hold the flat tappet end (part that rides the cam) against the side of another lifter at a 90 degree angle. Now looking at the tappet end with a light source in the background check if you can see light leaking through in the middle (concave) or sides (convex).

I hope that makes sense. :-)

 

Buzz, great posting. I am getting a fantastic lesson from this thread.

Also, I feel DM had a very good point regarding the quality of bolts available these days. We need to ensure that the desire to get the best price does not bite our tushes by giving us a less than desirable quality bolt for such critical applications.

 

If you're concerned about head bolt quality then ARP head studs may be for you. ARP Pro Series Cylinder Head Studs (Hex Nuts) Buick 215 cid, Rover V8 - Part Number: 124-4003 - Sparktec Motorsports

Personally I'm using them because the advantages I've read about while researching make sense, not because I believe the stretch bolts that came with the BP Allmakes kit are bad quality. Maybe they are, maybe they aren't. Haven't seen any evidence either way.
