\'02 Ventures use M8X1.25X98.5 exhaust manifold studs.
first install new carb gasket to intake manifold and then 4 nuts hold the carb to the intake studs and then install the throttle linkage to the carb.
If its the standard height, nothing. If they are screw in studs with tall nuts, then you will need tall valve covers.
Torque specs for the Chev. 3.1 intake manifolds are as follows:Lower Intake ManifoldCenter boltsStep 1 - 62 in-lbsStep 2 - 115 in-lbsCorner boltsStep 1 - 115 in-lbsStep 2 - 18 Ft-lbsUpper Intake ManifoldBolts & Studs - 18 Ft-lbsSpecs are taken from Hayes Repair Manual: Chevrolet: Lumina, Monte Carlo, & Impala (FWD) 1995 thru 2005
Bc. its a volkswagon and Germans engineers are brilliant the head studs are developed to provide maximum thrust at full capacity
Try the Torx bits onto the studs till you find the one that fits securely. Seems simple enough to me.
Unbolt from the block & take the nuts off studs to exhaust flange. You will need a new gasket for the block & a new one for the flange.
sell your van the studs for the maniflold are going to break and you most likely will have to replace head Between the exhaust manifold and the head is the manifold gasket. Where the exhaust pipe connects to the exhaust manifold is a manifold doughnut gasket.
19 lbs on the studs, and 30 on the nuts.
This largely depends upon the condition of the mounting studs. If they are clean, it's easy; if they are bad enough, they might require cutting off and new studs.
Yes, the studs break off of the head at the ends of the manifold.
V10 Left side exhaust manifold studs rusted away causing exhaust leak, 2002, 25,000 miles in motorhome.
yes. easy fix. http://the-hush.com/ this part makes repairing studs much easier. no redrilling or retapping of bolts.
You're going to have to drop both front and rear manifold connections. Should be 3 studs in the front manifold & 3 in the rear. Replace both o ring gaskets while you're in there. If the nuts on the studs are corroded then you might want to take it in to get it done because if you break a stud you will have more problems and higher cost to repair it. If you have accessto a cutting torch heat up the manifold to remove the studs or heat up the nuts as not to break the studs.
Depends on which one, there is an intake manifold and an exhaust manifold. The intake(normally aspirated)- you have to remove the air intake tube, throttle body, disconnect sensor, injector wires/vacuum hoses. Disconnect the fuel line to fuel rail, then you can unbolt the intake manifold. The exhaust manifold- is a little hard being against the firewall, you would have to disconnect the O2 sensor wires and exhaust pipe. I would spray the exhaust studs with penetrating lube. The upper nuts you should be able to get from the top, the bottom nuts you will need to get to from under the vehicle with a swivel and extentions.
Not much at a welding shop. You can buy the studs separate & screw them in or drillout the broken ones, rethread & then do that. Check Ebay for a used one-some times that's cheaper than messing with it, depending on engine.
hmmm a jeep wrangler it depends on the engine if this is a inline 6cyl with a 4.0 there are both 1 stud on each end of the manifolds and 1 in the center just so it makes it easier to install the bolt with the other hole if this is a v6 3.7L is should still use the same theory studs will be at the end of the manifold and regular bolt will be all in the center
remove the fender liner. probably have broken studs. they usually come out easily. a left hand drill bit works good if they're flush.
