Another “which camshaft” post
It rpm's fine just doesn't make any power up there and it's together and running, not in need of a rebuild just looking to add a bit more punch to it. but thanks for the suggestion
I forgot to add this story.
As a mechanic you can fix a lot of cars and just assume their outcome down the road based on text rule of thumb repeated/parroted cause / effect ...but I have 2 cars for an example of the old "new heads on old motor pushes oil through the worn out rings once the heads are tight at the seat,guide n seal... but I have 2 cars...one a '94 volvo w/red block with 322k and a '96 dodge 1500 4x4 w 299k
Volvo "burnt" a little oil, maybe a quart every 6 months and the Dodge ate a quart every month.. I changed the heads on both. I put a VX cam 11.5/10.5mm lobe vs old 9.5mm lobe, valve job,guides seals, weld up porosity n milled. The truck, ported sm magnums, positive seals,doubles, milled.
Both engines carbon was scraped off pistons. Truck pulls harder and almost 1000 rpm higher rpm. Neither lose oil now. Not a drop, no smoke, just more power.
The heads, the guides and condition of the seals is a ton of why and engine will burn oil. It sucks it in. It's very important the heads are in good shape, even if the rings turn out to be crap and it does smoke a little under load..it will guaranteed make more power with good heads.
