Team116 #2 cronicle 20th/21st March 2008

20/3/08:

Thanks to a wrecked 1971 GT Falcon we now have some much-needed high-speed downforce:

(Please excuse the tape holding the thing down - it was just a trial fit at this stage.)

21/3/08:

Have been meaning to pull the LHS cam cover off and have a look for oil starvation (the RHS is easy to check by looking in when the engine is idling for a supply of oil to the camshaft). Took it off today. Looks yucky but at least the cam lobes don't show any pitting or gouging, indicating oil starvation:

The oil distribution tube looked OK but was loose on one end, so I replaced the placcy end but with one with a bit tighter fit from the parts bin.

Question: Where are the oil drainbacks on these engines?, I can't see how the oil in there would drain back to the sump...

Its been about 4 days since I've run this engine, but even so the inside of the cam cover seems decided dry:

I can also see some scraping marks from the timing chain, but I don't know if this is normal or not...

That wing looks like a tidy fit Mav. Can't wait to see it fastened in place.

Not sure bout the timing chain marks on the rocker cover. I'll have mine off on Tuesday so will take some pics for comparison.


Has the oil pressure picked up since fixing that placcy bit on the end??
Eg.. on the gauge?.

Ian that boot spoiler looks like it was made for the 116.

I guess you will do some trial and error, I wonder what affect, if any the spoiler would have raised up a bit? with some spacers of some sort under it?



116's and fords of the period are fairly similar shaped, I've said before that the shaker scoop would look at home on the bonnet.

Bonnet scoops ay....

Bonnet scoops ay....

Yep

This one looks like it is enjoying 1970's ford braking technology,

 

[SELfor50]

Hahaha.... they had braking technology?!?

I reckon a bonnet scoop or 2 wouldn't go astray on a 116 racer..

mmmmm maybe like this then?

 

[Des]

Or like this......

I'd like air intakes like those..... but i'm thinking something with a little more 'wtf' factor.

WTF???

let me look through my pictures and see what I can find for you

You guys are forgetting this one. You wouldn't be able to pick your apexes if the star is obstructed.

Love the spoiler Ian.

The oil drain back holes are located towards the midline of the engine. Not sure how many there are. I know there's one towards the firewall end at least and of course some will track down near the timing chain.

Those scrape marks. Are they physical scrapes or just oil flinging off the chain causing a cleaned area? They look too clean compared to the rest you've pictured plus not in an area the oil would fling to I reckon. If it is physical, it's not normal but not sure whether it's crushed rocker cover seals causing the contact or a dodgy chain and/or tensioner.

They are physical - you can hear the clanking when first started until the chain tensioner pumps up and takes the slack out of the chain... it all sounds pretty ominous so i've bought a new chain without even measuring the old one... got a bargain JWIS chain for $90

From Noel's 450SEL d_jet I've grabbed the chain tensioner (side of the engine unit) and he's in the process of removing the sump and oil pump which, touch wood, will solve the oil pressure issues.

After much piss-farting around with points, gaps, timing, spark plug fouling, TDCs etc. this weekend I've finally got it settled down to a good 800rpm idle in Drive with 1.0bar on the Oel pressure meter which increases linearly as soon as you step on the gas.
