Help me! New rebuild. Low oil pressure. SOLVED!!!

[modok]

i hear ....want the cam to come in sooner, I think.....maybe what you really want is one step smaller heads/carbs/exhaust.
That's really what determines 'when it comes on".
The cam you can adjust, to a degree, how much is above and how much is below that.

But.......maybe not. it's an Ok setup as-is, really.
who knows what you'll like, maybe not even you.

86 A is a fine choice I'd say. The regular 108 lobe center should be fine, looking at valve sizes VS displacement and compression, so forth. I don't see any odd factors that need a tweaked lobe center.

I second what ^^^ modok said, but I add, do not buy the pre-clearance 86a (different cam blank) that does not go well with your lifters. Clearance the cam yourself, it is very easy to do. The web 86 is too mild for your combo.

You can also have extra duration added to the webcams if you want, acn does not mention this but they should instead of the lobe center thing. Adding duration can be a handy tuning tool.

On rockers? my favorite is the CB 1.4's and they give about 1.47 ratio. With an 86a that is about .490" lift.

Great thread, VW_Jimbo. Just read through the whole thing last night and this morning. As much as it sounds management BS to talk about valuing humility and teamwork and a willingness to learn, that's exactly how this thread got to a happy ending.

Can't remember.. you are running steel pushrods, right?

They are best set at a loose zero cold.

You can then check them at temp (fully hot) and see where they fall.

IMHO, if set at a loose zero cold,
And then the lash opens up to noisy,
Your motor is running too hot.

I'll say that I love my steel pushrods,
because of that nice zero setting cold,
They make less noise than aluminum pushrods do set at .006".

What was your lash set at, again??


Also,
What size is your exhaust?

My 1914 with 86b isn't a disappointing dog down low.
Can only imagine your stroker would be better..

What’s That Noise?!?

valve clatter will be increased by a hot engine and cold oil, since the push rod expansion is affected by oil temp. Engine growth by engine temps (not oil temps).

I don't even consider an engine warmed up until the oil hits 210F.

and yet we have to deal with manufacturers who have temper tantrums and blacklist us because we tell the truth about products, good and bad. They never mind the praise, but have a fit when criticized.

My clatter is less if set at .005 lash than if I set it tighter.
the key is make the actual lash match the lash ramp of the cam.
WEB uses a .012 lash ramp, when engine is more like .008
IMO web has it right

[Dan Ruddock]

Run stock pushrods? Don’t rev too or they will bend.

Dan

[modok]

I'm not advocating that it's a good idea.
I just wanted to see how long it would work with stock pushrods and hairpin clips too. And the answer is.....longer than most peoples engines.
It's been over 6k rpm hundreds of times, but probably not over 7k

Blame it on the oval wire conical springs.

John, you nailed it! Went for a two hour drive up and down PCH, several times. The valve train noise went from “I don’t like it”, to “it sounds like a vw”! It really sounded nice! So, now I know.

Now, I do wind out the engine while driving, so I will need to weigh out the pros and cons of what has all been written over the last few days. Ain’t going to happen this weekend or next week. My house is party central for the graduate!

[modok]

yes, sorry we got side-tracked. my point was -good quality- aluminum push rods do work very well, when sized right for the application

[Greg Ward]

1000%

Had Aircooled.Net AL pushrods in one of my engines since 2001...wouldn't have any Steel horsepower robbing things in them since!

I can't advocate for AL pushrods enough, some of my engines run to 10,000Rpm...
They all have AL pushrods...

Cheers,

Greg
