solid chain tensioners or Pressure fed??
I'm building an engine and the builder recommends solid tensioners because he feels they are foolproof as long as one adjust them when they get noisy. He has seen pressure-fed tensioners fail and knows of a recall of defective lot orders floating around. I have a set and I'm trying to decide whether to install the or not. Any mechanics out there with an opinion?
Thanks in advance
930 tensioners or pressure fed?
If you don't want to up grade your oil pump I would stay with the 930 tensioners. I would not use the solid mechanical tensioners under any circumstances! I have an early 911S and was told I would I would lose some oil pressure if I used pressure fed tensioners. Also at the time there was a back order sitution and that told me that maybe Porsche was changing the pressure fed ones. Also very important is using the newer Idler arms with the brass bushings as these will keep the arm from galling the shaft it sits on.
solid chain tensioners or Pressure fed?
I have a 1970 911S and wanted to upgrade my tensioners. At the time if I knew the tensioners that were in use had the hydrostops or guards on the shafts of the tensioners I would of kept them until they failed. I am very glad I did not know the statis of my tensioners at the time I purchased my car. I had to go into the engine and inspect the condition of the tensioners. I almost went for the pressure fed ones but several reasons against the pressure fed pushed me toward the930's. [1] There were some failures with the pressure fed's. [2] Lower oil prsssure with pressure fed's might mean less lubercation for engine. [3] possible oil leaks from added oil lines. [4] they are not used much in racing . [5] You loose the stock look.
Re: solid chain tensioners or Pressure fed?
Tensioners. I'm no mechanic, but I did the pressure fed upgrade some time ago. Ramps were changed at that time.
So far, so good, and I have not noticed any decrease in oil pressure.
That said, an earlier comment was uncalled for. something about "most of these dip****s don't have a clue", posted by a t150R. Uh, didn't the original post ask if "any mechanics out there with an opinion"? Yeah, I had an opinion, but I'm not a mechanic. How 'bout you, t150R? You a mechanic? If so, want to tell us where you work? Please, enlighten us mere "dip****s" some more. Can't wait to see a post as informative as Roland's...also without the insults, as Roland's post was.
