modifying cam duration

[TunedBy]

I was chatting to a mate of mine who said that you can modify the camshaft duration by applying some weld to keep the valve open longer.

pretty much stuffed my engine. i think you are better off buying cams instead of getting creative.

hah!

This has got to be a troll post...

Uhhhhhhhh. Lol. Wow. Some ppl shouldn't be allowed near a car...... or any type of motor for that matter.

[Matt93SE]

Niiiice!!
I saw a guy hoist an engine out of a car once by hooking a chain around the cams.
then again, it was a trash engine..

Did the cam caps actually hold the weight of the engine??? O.o and wtf to welding them?

[Matt93SE]

Yup.. it held. scary, but it held.

[Tower240sx]

that is fairly funny,

it looks as if the cams in the troll post were really welded so you could get a wrench to hold to tighten the cam bolts to their ungodly-for-having-such-a-****ty-socket tq spec

[Matt93SE]

Yeah, been there done that. I actually took a file to a set of my cams just to smooth the hex flats and give the wrench something better to hold.

either that or I'll use my good crescent wrench that locks down pretty well and has silch for play in the adjuster.

wait, u mean you guys don't use a pipe wrench?

i ground an old wrench so it would fit fully onto the hex on the cam. looked like this:



and it worked like a charm

I just used a 1" open end and a buddy.

[Matt93SE]

I used vice grips and an impact wrench when I installed the S13 cams in my car...

[leetfade]

I'd use the impact now! Didn't have one then and it was a PITA... It was much easier taking the cam gear off the junk yard Infiniti SR20 since I really didn't care if I ripped it out of time. LoL
