its funny i bought the bilsteins as an afterthought not really thinking i needed them. OMG did i need them.
im looking fwd to driving in the morning!
the fronts wouldnt expand lol. and i note there is a large difference in the diameter on the body. for the tear. and the fronts wouldnt expand either. haha.
i wonder how many c4's are driving around with pos struts. probably tens of thousand.

in reference to the shock install on the 84-87 with the bilstein HD (the z52 version (my car is base) as opposed to the z51 version) Id like thank everybody in this thread ,
Glad you swapped out the shocks! I did mine a few years ago and was amazed at what a difference it made. I think people see the low miles on the cars and figure they have to be good when time did it's damage before they could get miles put on them.
I was expecting about 25% of the improvement that i revieved.
I went out last night and put the car through the paces and it i would say that i would like an even stiffer (slower rebound) ride than with the HD version of the bilsteins. They are amazing yes but i want even stiffer of a ride.
this is a base car so ill leave them as is but im looking at a z51 to make it a streetable road course track car and i may end up going with a coil over conversion
i need a video about how spring rates and struts work.
Been a while since we've had an update-how's your car doing? Getting much drive time?
drive time...i wish. pretty snowy here.
life/work has been pretty demanding and i parked the vette and havnt done anything at all.
TODAY i start tearing into my valve covers.
there is quite a leak spilling onto the exhaust manifold so ill tear these out and refurb them and listen to helicopter ground school in the background. two birds one stone.
i ran my compression test on this 136k miles car and she is solid!
keep in mind im at altitude up here at the foot of the rockies.
this car has along crank and i suspected injectors. i could smell fuel on 3,2,6. and when i cranked for compression test with all plugs out i could smell fuel out the holes. i will do the furl line pinch test to verify snd isolate the injectors to be sure before ordering a new set.
you can see the line from fuelsitting im guessing.
VT, how many miles on the head? With the plugs out, I would do a leak down test to see how good your heads are.
My neighbor has a 87 dodge w250 truck with a 360 in it. I did a compression test/leak down test on it. We averaged 135-140 psi just like you and the leak down test showed leakage hi leakage bypass the rings. The 360 book says it has 8 to 1 compression new.
My 2005 LQ9 engine compression ranged from 190-200 psi, with almost no leakage. That's 10:1ish compression.
My 02 dodge D250 5.9L cummins diesel 24v is 400+psi in all six cylinders, with a low 457000 km's That's 18 to 1 compression
I did get the valve covers off last night and i found what looks like the remains of sludge in the engine. i have been using high detergent too tier oil (mobil 1) since purchase and i have achieved nice hot temperatures and i believe that the heads are very likely far cleaner now than if i had pulled the vc's off when i purchased the car a year ago.
In the low spot of the heads (iron headed 86) i found VERY dark oil, and buildup of sludge. some of which is magnetic no different than what a person would see adhered to a magnetic drain plug. the tip of my flathead is magnetic and you can see the material standing proud off the tip. the meagnetic material is not as big as it looks. but it stacks off the tip and makes it appear as shards.
My suspicion is that it is wear material from the rockers/pushrod/spring assembly.
if the engine had a high amount of sludge up here those metal components would not have travelled down to the pan.
anyway, engine runs strong with great compression (above) and leakdown of 5-7% which is amazing considering 220000 klms. 136000miles.
ugh. i HHHAAATTTEEEE rtv. cork and hylomar or blue rubber felpros ftw.
cracked snorkel
drip coolant from tb hose. dark dirty oil with sludge in low spots. oil changes have always smelled awful
i belive these tiny shiny bits have resided up in the heads for a long time and likely from rocker wear. thoughts? id rather not go through the process of removing rockers and resetting rocker lash. engine runs excellent.
