So another couple of weeks go by... Well, OK it was actually more like a month, but remember my feable mind was working
overtime trying to remember where I had put that bus engine case? Ah....yeah... I couldn't remember because none of the
cases I had available were machined for a bus. I had 4 in the machine shop, but all were type-1 application (no hanger bolts - bummer!)
So Son of reVOLKS begins commenting about the cost of oil being higher then the cost of gas and I get embarrassed and
admit I hadn't found an engine case suitable to correct the problem yet.
Son of reVOLKS says, he'll go with me to the yard and help haul one out of a bus, bring it back to the shop, do whatever
is neccessary and be eternally grateful if I'll just help him solve this problem...
Son of reVOLKS, his older brother and I pull out his original engine which is a
1600 dual port and set it up on the engine run stand, stripped down to the
bare long-block and start it up to see exactly what's wrong...
Remember I said that leaking oil from the top of the case is a bad thing? Well, it is. and in this 'case' it was a crack
along the case, just under the oil cooler's adapter mount (look at picture, just below orange seals, center of image).
This crack is unseen when the engine is not running. I wiped down the case with a solvent to rid it of grease and oil and then
when we ran it, a tiny hairline crack appears, oozing oil. When the fan-shroud was installed, this oil was being blown back
up ontop of the case and ran down the side toward the distributor....
So we pull a case out of another bus (ironically a 1970 also) and bring it back and Son of reVOLKS dismantles it...
The flywheel would not turn before dismantling, so I had visions of having to take it to the machine shop for most every kind of work
you can imagine...
However, the Vdub dieties were taking pity upon us at that moment and when the case halves seperated, it turned out that there
was probably less than 20 minutes of use on it. It was locked-up, because it had been assembled incorrectly and the main bearing
had been pinched by the case pin in the bearing's journal. :)
Yes! There is a heaven and I bet there are old buses parked in front with a lot of smilin' hippies still in them!
The case was so pristine that you could clearly read the bearing ink (denoting bearing's size) still.
The crank, the bearings and the case checked out to be STD/STD which still puzzles me, but they mic'd out clean, and true!
So I get a complete set of bearings out - crank, cam and rod. A gasket kit and set out to rebuild the lad's engine.
Everything went fine. The engine went together like it wanted to and by morning (oh yeah. long day in there that lasted
36 hours plus) the engine was ready to test on the engine run stand....
I awaited the arrival of Son of reVOLKS (whom I sent home to sleep about 1am after he
had cleaned and prepped the new case) and Mum who brought him back along with some much needed coffee as we started
the engine.
Ba-da-ba-da-Vrrrrrrm! It sounded great, timing was dead on, a clean start and run.
Did I mention the hot looking, sporty exhaust Son of reVOLKS wanted to put on
the engine?
Sor - "Ah...yeah...would it be a good thing to swap out that stock exhaust for ...THIS one?"
Dad - "huh?...(wrenching away not looking)...yeah. That's fine. Stock exhaust is restrictive anyway.
Header is easy horse power."
Sor - "Cool! this bus was so....."
Dad - "Bus-like before?" (more sleepy grins)
Sor - "Uhuh"
Net result, the case was cracked. We replaced the case and swapped over all the external components and it runs fabulous.
While the bus was on the lift after engine install we checked out the front end which was all great and I checked the transaxle
which was also doing great, but Son of reVOLKS mentioned that the back-up lights were
sporadic at best, so a quick meter check revealed a pooched back-up switch in the tranny and a few more minutes solved
that too.
The lad takes it out for a test drive and comes back 15 minutes later....
You HAVE to go out with me right now for a drive!
His Mum and I look at each other...."Why? What's wrong now?..."
We all four (oldest Son of reVOLKS was there too) hop into the bus and the lad heads
out onto the highway...
Dad - "Your shifting is very good son"...."the engine sounds great, if, loud with that exhaust"..."the ol' bus seems to
be handling well"...."what's the problem?"
Sor - "Ah...yeah... We're on the highway and we're doing the speed limit!"
Dad - "Annnnd?"
Sor - "It could never do that before! It maxed out at like 45, 50 if we were goin downhill..."
Dad - "So...this is a good thing right?"
Sor - "Ah...yeah...really good thing...Now I can go visit my MeMaw in Texas, knowing the bus will do highway speed!"
So the kid's heart is actually in the right place. He's been worried he wouldn't be able to drive this beater bus all the way
to his Grandmother's place to visit her on his spring break...
Parenting ain't so bad after all..
And this is today. Project "beater bus" is coming along just fine. The lad is actually a good driver. He's got his head screwed
on right. Doing well in school and anxious to actually tackle some of the cosmetically challenged panels on his bus soon!
Now if I can only get used to that aggressive exhaust sound coming from a bus :)
