Dipstick6:

You should be ok. My 96 said 5-30 on the cap. TO get technical 5-30 the 6 months of cold season and 5-40 the 6 month of hot season. BUT again, 30 or 40W will do the whole season

udidwht, I think I am saying the same thing you said. I would clarify a little by explaining to those who don't know. A valve lifter is a tappet. udidwht's first sentence could have been stated, "That vintage 454 came with a mild hydraulic tappet cam." The explanation of the difference between hydraulic tappets and solid tappets can wait for another time.

With respect to the tappets themselves. The solid lifter cam tappets were the ones with issues of wiping cam lobes flat during break in. It was suspected to be related to ZDDP but never actually proven. They also suspect it may have been related to metallurgy during cam billet processing (more likely).


This was what we were dealing with back in early 2000s in the ACVW world. A Type-4 engine builder myself.

I know I'm getting a little of topic but...

I used to drag race a little. Saw a guy at the track several times with a VW bug. I don't know which version VW engine he was running but it must have turned 10000 RPM.

He was getting 12 second time slips! For the mid 1990's that was a very fast car. It was temperamental and sometimes would die on the starting line!

What RPM's and HP did you extract from your Type 4 engine?

That was likely my buddy Lloyd Mosher (record holder) normal aspirated. With respect to the T-4 they can be built up to roughly 2.5L and not lose any reliability. While turning upwards of 8,000rpms @ 210+ horsepower.


Right now I'm running a 2056cc T-4 with dual Weber IDFs in my 72 VW Westy. On the dyno it puts out 98 horsepower at 120lb-ft of torque. In stock form with a 1.7 they were just shy of 70 horsepower. This is a mild build for a bus that can weigh 2,5 tons when fully loaded. What can be achieved with a T-4 engine can only be dreamed of with a T-1 upright.
