1970 s2 0453R Reassembly

[dakazman]

I received both of my heads back from the machinist 😀, I asked for his opinion again on the spare head after he deemed it garbage. He liked the idea of plugs 1/2 x 1 20tpi in head and was impressed I salvaged it. So he milled that head also. My search for bolts  that size sold by a local Napa dealer had only grade 8 . I may have a hard time drilling/ tapping and installing studs for manifold. I need to do a test bolt first.
 Some others items were to clean up rocker bolt holes, recut valve seats, clean lifters , pushrods , valves and springs. After some light lapping I’m ready to assemble head.
 I’ll be checking the crank for correct bearings but it looks like I’ll just need standard. I will also need a ring set for 77 pistons.
 On another front my vette engine head came back also and I installed it, getting thru the torquing sequence three times to bring it up to 65 ft lbs slowly was enough for one day. Still need to adjust valves and hook up lower header to pipes.
 One day at a time!

U-joints installed awaiting flingers / seals , then pressing in bearings. As Dave Bean manual states.., patience. I used NAPA P341’s. I will replace the longer grease fittings for shorter ones, I just think they come to close to the housings. Monday I’ll receive my s/s water lines 😀 from R&D 😀.
 Reinstalled my corvette head and torqued the rocker studs that were the reason for the bent pushrod.
Also installed.060 pushrods and polylocs.  Ran out of time as two water pump studs holding the fan on were missing, so I’ll be off to pick up some tomorrow.

You certainly have been busy!

It’s been raining a lot so I got a time off from painting the exterior of the house. The wife picked out some paint for my youngest daughters room that now is an independent woman living on her own. Painted it and even cleaned the windows 😀
We now have 5 empty bedrooms.

FIVE empty bedrooms!! However busy you are now, probably can't compare to how busy you must have been!

Dave, I can’t show my wife your posts as you always squeezing in painting around the house between automotive work. I only paint when I’m in the mood to do so. Don’t ask when that is as only I know it.

 Glen, That’s Okay. I also vacuum and babysit. Lol.
 
While waiting for more parts to arrive I assembled the rear drum brakes. Easy peasy! 😀
I can now comment on them. I found all my parts in the bins, ex ice cream containers, that were marked. Having all the parts I read the manual and said why wait. The first item was the adjustment screw assembly movement was nonexistent . Lubed it up and slowly worked everything loose . Cleaned and reassembled so now I can turn it with my fingers . I seriously recommend cleaning them.
 Installing the shoes and springs took 2 minutes to have mounted. Layout the shoes in proper orientation, flip over , attach springs top &bottom to both sides . Lift and place the shoe with the emergency bracket in place while keeping spring tension on. Pull the lower on side shoe Into place.
Keep tension on and pull lower after side in place , the the top. Put the mounting pins, springs and clip in place .
I did find that the backing plates are marked on the inboard top side as to right and left side.

 It never fails!
Another job to tackle, clutch job after 12 years. It’s amazing how big these parts are compared to the Europa. I know 400 hp compared to 86. Years ago I would have it out after working all night and in so to go back to work that night . It’s nice to be be retired.

You do have a thing about plastic cars, don't you D'man!

Good to know I’m not the only one bouncing around all my cars getting various projects done

Pulling engine tomorrow.😭
 My nbr 4 cylinder fills up with water. Crack in liner.  When the rocker stud loosed , bent pushrod pushed out the valve seat into piston. The same machinist built the Camino engine also. Now I’m thinking of pulling the covers and checking them also.

Ah Dave man that sucks, if your misery wants some company I have had to delay my Twin Cam Engine rebuild because my wife's 2011 Escalade no longer has any oil pressure and there were lots of shiny bits in the oil filter, just when I thought I was out of the woods getting rid of her Yukon with 430,000 kms.     I feel your pain...  But I have the day job still.

I guess I'll add my story here. My wife's '06 MB C230 recently developed terminal sprocket cancer. The engine uses a sintered sprocket for the balance shaft. On a string of them, the heat treatment was poor. (two errors here in my mind: using a 90° V6 requires a balance shaft, they should have used a 60° V and if they were going to use a 90° V, they should have used real steel instead of sintered steel for the sprocket) MB offered to help reduce the cost of a $10,000 (MB rate) repair by a few thousand dollars IF you were a regular customer of their shop. We felt lucky to sell it to a wholesaler.

 I all most don’t know what to say.
Rosco,  that’s going to tie you up for a couple of months. Time is the real enemy.  We’re mechanics because things break, we have the talent to make things right, which most people can’t do.
  BDA, wow. Glad that you did get out! I was wondering why I saw a few cheap mb c230 . We all most purchased one for my daughter but on her test ride something started making a weird noise. She got a Honda Civic sport 4door.
  I’m sure we will all still run into bad purchases that were no fault of ours. All the electronics items break at the worst possible time . I HATE throwing away items, I consider myself not a part of that throw away society.  Sorry ranting again! It all comes down to a prayer I have copyright to,
For the joy after the sorrow
For the laughter after the tears
For the health, food, and shelter through the years
We thank thee oh lord.

It's not all of the V6 MB engines but just a subset of them. I think they got things squared away for the 2007 year but I'd still be wary. An MB dealer should be able to tell you if that car has the issue - and I think they will if you ask - but it's really soured me on the vaunted German car industry. It seems like the Japanese and Koreans make the best cars now.

Love the prayer!
