BLACK LEGEND II

Discussion Starter · Nov 28, 2001

Hi there, I'm planning to change my hydraulic lifters on my 92' 1,8 8v GTI this week-end (a bit too noisy) Whilst doing this how easy is it to put in a performance cam. Will it be an expensive operation (I dont have much cash to spare) Will I have to put in new valves, stems and seals or can I just put in the new cams. Could you please show me the way.
Thanks in advance!!!

Re: PERFORMANCE CAM (BLACK LEGEND II)

I installed a TT 268 cam in my 91 GTI 8v and it was very very easy. Now I do all my own work so this was not exactly the first thing I have done but it will be easy for even a rookie. While you are in there doing lifters and such it will be no extra work. You will have to take the cam out anyway to get to the lifters. I never changed my lifters, valve seals, springs, valves, etc. when I did my cam. I just popped in the cam and drove one. Oh make sure to use plenty of assy. lube when you do all of this. What cam are you thinking about getting? I think I got my TT 268 for $120. Thats pretty damn cheap for a camshaft so you shouldn't have a hard time finding a deal.

Re: PERFORMANCE CAM (BLACK LEGEND II)

installing a cam is super simple and involves next to NO extra labor if you are changing lifters, no need to change springs unless you go crazy (huge cam).
keep in mind the cam can actually hurt your performance if you dont have a preformance exhaust on your car.

Re: PERFORMANCE CAM (BLACK LEGEND II)

If you're installing lifters you're pulling the cam out anyway. Do the valve stem seals if you want to keep the car for a significant length of time and don't plan on building a bigger motor which would involve rebuilding the head anyhow. (So basically 'do as I say not as I did'.

)
And if you do install a new cam, make sure to break it in like Illusion says. Most cams come w/ break-in instructions.

Re: PERFORMANCE CAM (BLACK LEGEND II)

I didn't break in my cam at all. I would recommend breaking it in but I have had no problems at all. I did let it idle a few minutes but nothing close to 10 mins. at 2K rpms. What I did was more like 1100 rpms for 5 mins. at the most. But if you do a cam break it in.

Re: PERFORMANCE CAM (BLACK LEGEND II)

The Haynes manual actually has the best description of the cam swap (far better than the Bentley), strangely enough. Easy job, just make sure that you get the cam timing right. On the lifter issue: Here is an old tip for noisy hydraulic lifters: Run a quart of Automatic Transmission Oil (ATF) with the motor oil for a few hundred miles. ATF is 20w oil with super strong detergents that can clean the gunk out of the lifters, oil control rings, etc, etc. It might be all that is required to get rid of the lifter noise.
My car was consuming a quart of oil every 750 miles due to gummed up rings. I ran some ATF for a while, and oil burning was reduced to almost zero. Very impressive stuff. Give it a try.
