We built this engine for Aaron over 2 years ago but he only has about 500 miles on this engine as of the last 4-6 months.
He started having issues with it so we pulled it to take a closer look at what's going on. Originally this was a very tight budget build, only replacing parts that had to be replaced.
Watch as we go though the process and probably dive into a bigger engine build for his beetle.
Thank you for watching.

@ChipsAndSparksGarage Год назад

I see he has a serpentine belt tensioner on the block. I’m not too familiar with that setup for a VW and don’t know how much stress it puts on the crank snout. Could that have contributed to the bearing failure? Good video, Gary. This is how we learn!👍

@VWJawbreaker Год назад

I’ve talked to many people and the serpentine setup seems to be split 50/50. I can say that the belt was way over tight by someone else who changed out his alternator and a few other things. I do believe that contributed to most of the damage. But then again, could be other things as well.

@vwmountainman9701 Год назад

I had to rebuild one engine 2 times. Everything good - fire up & run for break-in. No apparent issues. Upon restart - no go !!!! Both times - bearing issues Now - I order 2 or 3 sets of bearings. To get hopefully - one good set. Shouldn't have to do that - but that is what's it's come to.

@VWJawbreaker Год назад

You’re so right, it shouldn’t be that way but unfortunately that’s how things are going now.

@vayabroder729 Год назад

I love 90.5s. A single port 1776 built up right is a peppy torquey motor. For internals you can never go wrong with Scat, Gene Berg or DPR.

@VWJawbreaker Год назад

Yes sir! Reusing the C25 in this will be nice. I did a similar build a while back with the Engle 100 cam, man it’s a beast even with a single 34/3 carb on it!

@martinharris5017 Год назад

This is what my engine looked like before I rebuilt it. The wobbly bearings at each end and a ton of concentric play! My 1600 sp is a budget engine, almost totally home-assembled. Almost. The one part of the engine I handed to a pro was the case. I asked for an align-bore. He said "It will cost you, and I INSIST you give me your case, your new bearings, and your new crank." What he did was remove all the oil galleys, hot-flush the case, perform the align-bore, install the bearings and match up all the oil holes, check the crank runout, and then grind the bearings and crank together for "zero misalignment". When he gave me the quote for the work, he saw me choking. he sat me down and said, "either you take the risk, just chuck your bearings and crank in and then install your nice cam and heads etc, and you'll be back in a few thousand miles with a wrecked engine, or you spend the money on the bottom end NOW and never have to open that case again. You can spend money on the top end as and when your budget allows and have total peace of mind that your crank and bearings are good for the life of the engine." And he was right. It cost money, but it was worth it.

@VWJawbreaker Год назад

Excellent points as always! I agree with the builder. It does suck to spend that much up front but in the end it’ll be worth every Penny!

@FixinBugsNStuff Год назад

After market parts are seriously suffering from POOR QUALITY mostly coming out of CHINA. After market CAM SHAFTS is a good example as MANY suppliers are seeing these camshaft lobes wearing down in a few hundred or thousand miles due to no or very little HEAT TREATMENT. A professional LINE BORE and a GOOD set of bearings should fix this and NO on the serpentine belt!

@VWJawbreaker Год назад

Many of us have been seeing the same things and it’s been getting worse over the last few years. Other case is being line bored. I’ll fit up new bearings to the crank and case and I’ve already talked him into ditching the serp belt setup.

Yes my friend that is what I’m going thru. I can’t find a machine shop to line bore my case so Looks like new case. Do you think that if my fan belt was to tight that would make the endplay worse? I try not to ride the clutch at stop lights. Just looking for someones brain to pick. Thanks for your great video as usual. I love your humbleness. You always stay Positive.

@VWJawbreaker 11 месяцев назад

If you’re going with a new case I prefer the super aluminum cases vs the magnesium cases but that’s just my opinion. Tight fan belt won’t make the end play worse, it’ll wear out the case nose main bearing. Hard to say why you’re having an end play issue, could just be a worn out case…. They’ve been through a lot in 50+ years.

@Demop_VW_garage Год назад

Wonder if its the alloy crank pulley and serpentine belt? A few engine builders I've talked too will not use them because of the damage they can cause to the case. They come loose and slap the inner case surface.

@VWJawbreaker Год назад

The person who installed the new alternator definitely torqued that belt, I have a feeling that’s what contributed to the majority of the issues.

@martinharris5017 Год назад

They only come loose if not torqued correctly (and preferrably loctited).

@VWJawbreaker Год назад

@@martinharris5017 honestly with the amount of contact surface the serpentine belt has vs a standard v belt, you don’t have to hardly put any tension on the belt tensioner.

Got a couple questions, if you don't mind... I know my build I went from stock 1970 block to 1776 90.5x69,and big valve heads and Engle 100 tiny cam my rocker shafts had to be shimed .130 .iam thinking wtf .so I am leaning towards cutting pushrods.130 tho?

@VWJawbreaker Год назад

It’s not so much the fact you went from a 1609 to a 1776 but the difference in the aftermarket jugs. There’s a variance I’ve seen between some different sizes in deck height. If you were able to shim the rockers to obtain the proper valve geometry, you could leave it at that instead of cutting new push rods. Up to you but either will work as long as you have plenty of threads for the rocker arm nuts.

@vayabroder729 Год назад

@@VWJawbreaker Right on; this is something that needs to be mocked up and measured. Sometimes shims are the right solution and sometimes not.

@VWJawbreaker Год назад

@@vayabroder729 I don’t mind a small shim if needed only because I hate cutting push rods. However, if stacking multiple shims is the only way to get the geometry right, then the right way is to cut the push rods.

Ten to twenty thousand for no-expense street motor sounds about right. By doing almost all the work at home my engine comes in at about 2500 NZD. That includes $1000 on getting a GOOD engine builder to do the align-bore, thrust-cut and crank-to-bearing custom fitment.

@larrymcgarage2152 Год назад

I don’t understand why he would want to go single port. If he wants more power, it makes no sense, except to save money on intake and carbs. If it was mine I’d spend the extra money. Even a single 40 Weber would make more power than dual single port carbs.

it has been said ! even a well ported single port aint got the volume of a stock dual port !!!!!! he would have to get dp intakes and those carbs would still work .
