Aaron's Volkswagen Beetle 1776cc single port engine build.

Last video we tore down Aaron's 1679cc engine and found some issues.
He ended up getting another duel relief case already cut for 90.5mm cylinders. I took his single port heads since they are in great shape and had them opened for the 90.5mm cylinders and also had the case double checked and hot tanked.
We were able to reuse his crank, rods, cam and lifters from his old engine into the new 1776 build. It didn't take much to get this mocked up a few times and then final assembly.

Nice work Gary! Pro tip- remove the rocker assemblies and spark plugs when you are priming the engine for oil pressure before first startup. That will keep the extra pressure off the rod bearings and cam until oil pressure is built.

[@VWJawbreaker]

Good point, that’s something I usually don’t do.

@@VWJawbreaker I think we share the 'not afraid to try even if I get in too deep' mindset. My problem is I can't seem to find the time. My wife keeps threatening to sell my sunroof '67 and I keep begging for stays of execution. So far so good.

Thanks again Gary great info.I will be doing a first build in the near future. When you lap the heads to the cylinder is that all you need to seal that surface. Thanks again.

[@vayabroder729]

You don’t need anything else, some use copper spacers there to tweak the compression ratio but that is also done with the shims at the bottom of the cylinders just like Gary did here.

[@VWJawbreaker]

That’s correct as Vay stated above.

[@ChipsAndSparksGarage]

Just in time for me, before I finish my 1776! Did you use ratio rockers with the C25? I’ll be using 1.25:1 and lash caps. Great video, as always, Gary👍

[@VWJawbreaker]

Thank you sir. I used stock rockers but in the solid shafts doe the the HD valve springs. I’d love to see an update video from you 😎

[@plymouths1]

Awesome video Gary, it would have been helpful before I built my 1776. I see you didn't use ratio rockers and cut moly pushrods, that's where I had problems with my engine and went back to stock stuff. After I got it together I read that having stainless valves with stock rockers can distort the stem, do you think that will be a problem down the road for me?

[@VWJawbreaker]

Rockers on the stainless valves can cause the valve tip to deform, they make lash caps that go over the end of the valves to prevent that from happening.

[@plymouths1]

@@VWJawbreaker but do I then have to use shims and use cut moly pushrods like I was using ratio rockers

[@VWJawbreaker]

@@plymouths1 usually just rocker shims.

[@Slick56]

Gary is right lashcaps on the ss vales. You need steel or hd aluminum pushrods if have dual valve springs. Most ratio rockers require custom length pushrods as do wider or narrower than stock engines.

[@VWJawbreaker]

@@Slick56 thanks as always for chiming in with your expertise.

[@vintage76vipergreenBeetle]

I would have stayed with the 0.055 deck height. Stock 1600 left the factory with 0.060. 0.094 deck height, is going to make the engine run hot, and hard to tune. Just my opinion.

[@VWJawbreaker]

Hey buddy. I hear what you’re saying however these heads have smaller combustion chambers and the compression would have been too high. I know people who have ran .090 shims under the cylinders and haven’t had a heat issue before. I also ran this info past a few others and they agreed this setup would be just fine.

[@vintage76vipergreenBeetle]

@@VWJawbreaker ✌

[@vayabroder729]

I believe the higher the deck height the lower the compression ratio and the lower risk for the motor to run hot. Motors can tend to run hotter with higher compression rations.

[@VWJawbreaker]

@@vayabroder729 especially when the compression ratio is higher than the cam manufacturer calls for.

[@txgunslinger]

You need to get crackalackin’

[@VWJawbreaker]

Story if my life 😂

[@craig162]

Why not switch to dual-port heads ? I thought Single-port heads and the intake manifold were supper restrictive. I have seen you build a few signal port engines. Am I missing something ?

[@VWJawbreaker]

Well, he didn’t want to switch to dual port heads, that’s why he stayed with single port. Single port heads breathe just fine depending on what you’re trying to achieve. They do produce a little more low end torque but they won’t get the same high end rpm’s that a dual port will. Many busses still run built, larger displacement single port engines.

[@trevcessna1723]

Hey Gary, do or can you use Aviation Sealer on the cylinder shims? Great job, thanks!

[@VWJawbreaker]

You can but I’d prefer not to only because it’s no where as good as it use to be imo and you need something that will seal better in that area so you don’t develop leaks.

[@trevcessna1723]

Ok thanks… what do you use?

[@VWJawbreaker]

@@trevcessna1723 I prefer the ultra black.

[@EmmettRacing]

Single ports aren’t bad engines! It’s only missing a turbo.

[@VWJawbreaker]

Haha, doubt he’ll want a turbo.

[@triariicat8448]

What compression would .095” deck height run with? That cray cray imo

[@VWJawbreaker]

Single port heads have smaller combustion chambers than stock dual port heads. It’s all about the total combo.

[@triariicat8448]

could I run 8.3 with single port heads with .040” deck height? You know, the world is going to end of it’s not .040” deck height lol

[@VWJawbreaker]

@@triariicat8448 8.3 cr would depend on the cam shaft being used. Look up the cam you’re using to see what they recommend for a compression ratio. .040” deck is an absolute minimum to run without the chance of valve to piston issues.

[@triariicat8448]

@@VWJawbreaker yeah the website says it’s good for 8.1-8.3 CR, just wondering if single port head could handle it

[@Mr69volks]

Would too much compression cause excessive blow bye?

[@VWJawbreaker]

Doubtful, blow by is usually caused by worn rings / cylinders.

[@Rodrigo-pb2rx]

nice work sir, excuse me whats your final torque number for the heads? greetings from mexico

[@VWJawbreaker]

All depends on what size head studs you have. Bently manual calls for the following: 8mm - 18ft lbs 10mm - 23ft lbs

[@Rodrigo-pb2rx]

@@VWJawbreaker thanks a lot , i have 8 mm studs, just want to confirm

[@jimmywilkinson9190]

Hey Gary ! on the oil cooler mount does those grey thick paper gaskets work there ? Just saying remember what happened to the engine VW Darrin took apart . the rubber had squished closed .

[@VWJawbreaker]

Hey buddy! I don’t recall seeing paper gaskets for the oil cooler or oil cooler mounts. They all take the rubber seals. As long as you don’t over torque then I’ve never had an issue. Another reason I prefer to watch the oil pressure when the engine is running and verify the oil cooler is working and pressures are good.
