Engine Mechanical problem
2001 Kia Rio 4 cyl Front Wheel Drive Manual

blew head gasket, had repaired at machine shop, replaced all gaskets, new timing belt, new plugs, new wires, new cam sensor, new coolant sensor, new thermostat, timing is correct but vehicle wont start, compression is as follows, #1 cyl 50, #2 cyl 60 # 3 cyl 60 #4 cyl 100, what could be wrong.

Hello. Thanks for the donation. Much appreciated

You have no cylinder compression. Each cylinder should have at least 150 psi @ cranking (3 revolutions). Check you have the head tightened correctly

COMPRESSION SPECIFICATIONS
Compression Pressure
Rio.184 psi (1275 kPa)

Can it be 180 degrees out of time? What position should the dowel pins be located on the intake and exhaust cams when installing the sprockets, either 12 o clock or 6 o clock? Thanks.

Install camshaft pulleys onto camshaft aligning "I" mark with intake camshaft dowel pin and "E" mark with exhaust camshaft dowel pin

Installation
Install tensioner pulley. Pull tensioner pulley to its furthest point, and tighten lock bolt. Check that timing mark on crankshaft sprocket is aligned with timing mark on engine. See Fig. 2 and Fig. 3 . Ensure that camshaft sprockets are aligned with marks on cylinder head cover. See Fig. 4 .
Install timing belt onto crankshaft sprocket first, then idler pulley, exhaust camshaft sprocket, intake camshaft sprocket, and finally, tensioner pulley. See Fig. 6 . Ensure there is no looseness in belt between idler pulley and exhaust camshaft sprocket, or between intake and exhaust camshaft sprockets.
Loosen tensioner pulley lock bolt, and allow tensioner spring to apply tension to timing belt. DO NOT add additional tension. Tighten tensioner pulley lock bolt to specification. See TORQUE SPECIFICATIONS .
Rotate crankshaft two full turns (clockwise only), and align timing mark on crankshaft sprocket with timing mark on engine block. See Fig. 6 . Ensure that marks on camshaft sprockets align with marks on cylinder head cover. See Fig. 2 , Fig. 3 and Fig. 4 . If marks do not align, remove timing belt and repeat process from tensioner installation.
Measure timing belt deflection by applying moderate pressure midway between camshaft sprockets. If deflection is not 0.39-0.50" (11-13 mm) with 22 lbs. (10 kg) of force applied, repeat installation process from tensioner installation.
Install lower and upper timing belt covers, timing belt guide plate and crankshaft pulley. Install water pump pulley. Tighten all bolts to specification. See TORQUE SPECIFICATIONS .
Install generator belt and adjust tension. Install power steering and air conditioning drive belt, and adjust tension. Connect negative battery cable.
