That might work on the KA, but would spell trouble on the VH. Replacing them with the metal backed version is a must .sensibleS13driver wrote:yes original chain guides :/ naturally i want the car for myself but that doesnt seem to be in the cards, i would remove the guides if it were mine.
Common thing on the KA is to simply remove them.elwesso wrote:Unless when he said remove he meant R/R

I had a 90 240sx with that KA engine. Had a blown head gasket so I pulled the top end and had it totally redone. Saw that the timing chain guides were plastic & had broken to pieces. The chain then wore a grove in the aluminum timing chain cover badly enough that I purchased a new one along with the new/updated guides with metal backing. I could not imagine just removing the chain guides in the KA as the chain has too much slack. If you get into the engine that far, why not just replace them? MUCH easier job than the VH engine.Rex wrote:Common thing on the KA is to simply remove them.
You're thinking of Marin Ave, and no you don't cook your brakes coming down that hill, uninformed exaggerationtexasoil wrote:The SF Bay area can be extremely hard onbrakes and transmissions. The steep hills do work things over real hard, depending on the particular driving routes. Try driving straight down 'wildcat hill' --from Berkely directly toward the Bay--straight, dropping very steeply--only a BMW,Prosche,or Brembo equipped car will make it without cooking the brakes.
It's a little different with the dohc ka engine vs the sohc. On the dohc you can remove them, this is not the case on the sohc. I also replaced them on my sohc when I had it.Mark86T wrote:I had a 90 240sx with that KA engine. Had a blown head gasket so I pulled the top end and had it totally redone.
