Timesert Kits

dpitman9 · 07-25-2010, 11:08 AM

I am in the process of rebuilding my '80 SC engine and have found that I need to install Timeserts for seveal cylinder studs that pulled out. Does anyone have the Timesert kit number that is used for this modification?
I am planning to use Raceware studs as replacements.
Thanks in advance for any guidance you can supply.

If I may offer some advice,.....

JMHO, but you'd be much better served by using CaseSavers instead of Timeserts for head studs holes. Timeserts are OK for the other, less critical stuff.

Further, I'd not use Raceware or ARP head studs due to major differences in expansion rates between these and the factory ones. Everyone has opinions about this so I'd recommend doing some homework on this important subject.

Rule one. Listen to the Steve.

Rule two. See rule one.

That said, check out Keen certs. They are a nice piece of kit. Mcmaster even has them.

Thanks for your input - and, as I am sure you know, everyone has an opinion on the various studs drilled holes for the available and what should be used to repair the o/size threads. At this point I followed the advise of a local PCA technical advisor who was very emphatic about the use of he Raceware stud assemblies which I bought. After trying them in the stud threads I discovered that I have three holes that will need to be repaired. The Raceware literature advises the use of the Timeserts as opposed to Case Savers. I know our hosts (and obviously, Rennsport) are more in favor of the Case Savers. I have noted that the drilled holes for the Timeserts are about .070" smaller than the Casesavers. That is a consideration when working so close to the cylinder bore.
Anyway, here I sit with a very expensive set of studs looking for the best option for an insert repair. I plan to talk to Raceware tomorrow and get a confirmation of their advise before I order anytning.
Again, thanks for your input.

There is a Kit on Ebay that includes 5 inserts I do not know if this is the exact kit for your engine, he has several.

Porsche &V.W Case Studs Part # 1085: eBay Motors (item 280429911160 end time Aug-23-10 20:00:51 PDT)

He also has a ten pack of "refill" inserts and a install guide plate for ~$10.
I am rebuilding a 2.2 engine (MAG case) with no pulled studs and am considering if I should install installing inserts in all head stud positions. With the guide plate it looks like something I could do at home.

I looked at that ebay link and the timesert kit pictured is missing the tool that makes a stepped counterbore at the top of the hole the time sert screws into.
thats why there is one empty slot in he plastric case.

Timeserts have a little shoulder at the top and that tool is needed for cutting the counterbore recess for it.

I have the 8x1.25 and 10x1.5 Timesert kits and I paid around $80 each for them new.

Google them, and you'll find suppliers.

I stumbled upon a crossed #1 plug that was , ultimately,drilled out. I speacifically asked for TimeSert repair on this (engine down) ,.....however, KD stuff was used,...I changed the plugs out at the 1K mark and the damned insert came out with the #1 plug...not cool.

Mechanic has agreed to (re)install a TimeSert sleeve in there..gotta' get the necc'y tool pieces , however.

...geeze.
