My '91 744 B204GT project

[tomasss]

Well I definitely don't want to do something incorrectly especially in these early stages of the engine assembly...if I do, I would have to take the engine out again. So I appreciate all these hints what I could do better
But yeah, last time I sealed the head halves without the roller and it was running just fine, with no leaks etc. And on disassembly I saw that the sealant was spread evenly across the surfaces of the oil passages with minimum overhead, so I believe it would have been just fine as well

It will I build many engines without roller :p

if its fine for you, then it is fine, but i suggest anybody to do it with a roller.. you can easily overdo with the gue and a blocked oil passage is the **** if you could have avoid that with a 3,50€ roller :b

[tomasss]

What kind of roller do you use? I cannot find anything car specific, is that just a normal roller for painting walls?

[oldschoolvolvo]

I used a small roller for painting walls. Something like this:

i used a PU roller for wallpapers, it is not spongy

[tomasss]

Not much has been done as I have been spending time on some amazing hiking trips around the world...but at least something. The rusty master cylinder has been visually irritating me for some time as it was the only remaining rusty thing in the engine bay. Originally I just wanted to repaint it but lately I've decided to replace it...to make sure the old seals don't let me down.

Old one out


Side by side


New one in


I have bench bleeded the new one, also I've bought the pressure bleeder so I just need to get some brake fluid and bleed the system again.

And this is how Christmas in September looks like

[MadDog_945]

mhhh the fourth of advent.. isnt it lovely? :D

[tomasss]

So...piston rings installed, also the conrods from maxspeeding using the assembly lube. Fit is nice and tight without any machining required, looks good so far!

What brake booster and adapter is that?

Just a bone stock 3516093 booster...also the adapter I believe is stock, it was all like this from the very beginning.

Very nice project so far.
I'm rebuilding a B234F of a 940 to a B230F to be used in my 242.
I dessembled the B234f engine this week to have it all measured en the heads cleaned. I'm gonna pick up a late B230F soon, which is going to be the bottom end.

Did you do some upgrades to the head (valves or lifters), im not sure if i should upgrade someting there now im at it.

INA hydros and ford 4.6l springs

Yes, cheapest option.

INA hydros is what I have used too. What is the benefit of the ford springs? Somehow I have missed this upgrade but I could still easily do it as the head is apart...

PS: ok already reading the threads...https://forums.turbobricks.com/showthread.php?t=197187 and http://forums.turbobricks.com/showth...190475...where do you get the VS1632 springs nowadays? I just quickly checked the rockauto, ebay and some local shops with zero results...

As far as I understood the head is quite good for the power levels I am aiming (300-350hp) so there were no real upgrades, just cleaned everything and replaced what was worn (lifters, seals, valve stems).

[tomasss]

Well after some research it seems there is a replacement of the VS1632 spring with a part number VS1268. It shows both in the rockauto catalog for 4.6l ford engines and in the interchange part number table (VS-1268, VS-1632 being the same).
Can someone confirm this?

[oldschoolvolvo]

I used the VS1268 springs in my 16v head. Runs fine.

[tomasss]

So the pistons above are unfortunately too small for my engine because of some misunderstandings. I am getting a new set soon and these are for sale with discount

[dopski]

To bad it isn't a 2.3 diameter.

Thanks for the INA hyodrolic lifter tip, they are quite cheap @ daparto.de.
Because i'm building an NA motor i think i will keep the stock springs.

Or did you find some affordable in EU?

[oldschoolvolvo]

Looks like ~50 USD shipped to NL from RockAuto for 16x VS1268 springs.

Awesome; just to be 100% sure I've sent a question to the manufacturer to confirm the VS1268 and VS1632 are exactly the same and there is no advantage of using one over the other one. I am ordering it right after the confirmation

[tomasss]

New piston set will still take few weeks, so in the meantime I am taking care of the 3rd gear mod of the M90 the transmission is apart, now waiting for the gear puller and then the ring will be welded as discussed >here<.

Oh, and also the VS1268 Ford valve springs are on the way
